Welcome to the eighth episode of Forward of Its Time, an authentic podcast from Setapp in regards to the tech underdogs nobody realized would form the long run.
Facial recognition virtually appears like a scorching pattern that emerged previously few years. Little did we all know that it was invented by one Woody Bledsoe again within the Sixties! On this episode, Shaun Raviv unveils the reality about Bledsoe’s work and no matter it needed to do with the CIA.
Then Karthik Kannan shares his expertise of constructing on prime of facial recognition know-how to assist visually impaired individuals navigate the world. Utilizing Google Glass, his firm Envision created glasses that may acknowledge faces and supply visually impaired customers with all types of insights about their visible environments.

Transcript:
Julia Furlan (00:04):
There are numerous particular person quirks and traits that make you totally different from the opposite 7.9 billion individuals on Planet Earth, however probably the most seen distinction, the factor most intimately related to your particular person id is indisputably, your face. We intuitively know that everybody’s face is exclusive, however what’s more durable to know and to elucidate is precisely how one face is totally different from the subsequent.
Karthik Kannan (00:34):
Faces are totally different, however they’re additionally the identical, proper? They’re distinctive and the identical on the similar time.
Julia Furlan (00:40):
That is Karthik Kannan. He spent the final a number of years measuring and quantifying the human face to assist make the world extra accessible. In 2017, Karthik co-founded a facial recognition and laptop imaginative and prescient startup referred to as Envision.
Julia Furlan (00:52):
They make AI assisted software program and glasses that assist the blind and visually impaired navigate the world. Throughout his journey to digitally replicate the invisible computations our eyes and mind carry out numerous occasions a day, Karthik was amazed to be taught simply how a lot data we subtly talk with our facial expressions.
Karthik Kannan (01:12):
You look somebody within the eye and you’ll actually know what their true intentions are once they’re speaking to you. You realize in the event that they’re mendacity to you or in the event that they’re glad or they’re unhappy. There is a inform within the face. And that nuance is one thing, I believe, until date AI struggles to essentially seize.
Julia Furlan (01:27):
However AI is already fairly good at figuring out totally different photos and patterns. And the glasses he developed can acknowledge objects, learn textual content, and supply a voice description of what is taking place round the one that’s sporting them. Karthik will not quickly overlook the day they first got here to life.
Karthik Kannan (01:43):
We have been simply sitting on this room and I am placing on the glasses for the primary time. And it simply begins talking out textual content that was in entrance of it. After which it was capturing all that data after which talking it out to me. It was insane.
Julia Furlan (01:55):
And up to date advances are serving to these glasses do greater than acknowledge objects and browse textual content. Karthik has programmed them to acknowledge and describe human faces. This has large implications for visually impaired individuals who utilizing this know-how, can dwell a extra impartial and socially related life.
Julia Furlan (02:14):
These exceptional glasses are a part of a rising regular torrent of innovation in facial recognition know-how, which extremely sufficient, date again greater than half a century to a comparatively unknown mathematician and laptop scientist named Woody Bledsoe.
Karthik Kannan (02:29):
I used to be studying this text about Woody Bledsoe. He stated, I might see it or part of it in a small digital camera that will match on my glasses that will whisper into my 12 months the names of my associates and acquaintances as I met them on the road. For UC, my laptop pal had the flexibility to acknowledge faces. And it is much more eerie that 60 years later that I am simply sitting and studying this paragraph and I see it precisely match with what we’re doing at Envision.
Julia Furlan (03:06):
I am Julia Furlan and that is Forward of Its Time, an authentic podcast from Setapp, a present in regards to the tech underdogs nobody realized would form the long run. Setapp’s versatile app subscription service empowers you to step into a brand new period of productiveness. Karthik first discovered about Woody Bledsoe years after beginning Envision, and in all probability, he would most likely nonetheless do not know who Woody Bledsoe was or what he did if it weren’t for a person named Shaun Raviv.
Julia Furlan (03:43):
One morning, just a few years in the past, Shaun Raviv wakened and made a beeline for his laptop. The Atlanta based mostly journalist had an concept for a brief story about facial recognition, which got here to him in a dream. He obtained began by researching the historical past of facial recognition. And what he would quickly uncover was extra attention-grabbing than any piece of fiction he might have dreamt up.
Shaun Raviv (04:04):
And I began Googling and I discovered some very, very bizarre reference on a extremely unusual web site to Woody Bledsoe as being the founding father of facial recognition. However there was little or no on the market. There’s virtually nothing to examine him that was attention-grabbing on the internet. Mainly nothing in any respect.
Julia Furlan (04:22):
Quickly after he began his analysis, Shaun was in a espresso store when his cellphone rang. The voice stated…
Speaker 1 (04:27):
Hello. I am Woody Bledsoe’s son. You despatched me an e-mail?
Julia Furlan (04:30):
As Shaun stepped out to take the decision, Woody’s son started to inform him an intriguing story. Early one summer season morning in 1995, Woody’s son stopped by his dad’s house in Austin, Texas for a go to. When he arrived, he noticed Woody was sitting in his storage, door open ready for him. At this level in his life, Woody was extraordinarily sick. His physique ravaged by a degenerative nerve illness referred to as ALS. Woody’s thoughts, nonetheless, was nonetheless sharp, however the illness had robbed him of his speech. So he wanted to speak utilizing a small whiteboard.
Shaun Raviv (05:06):
He walked his son to a secure in his storage and he wrote down the mix for his son. He could not consider his dad nonetheless remembered it. He opened it and there was a bunch of previous rotting papers, basically. He by no means knew what was in there. And his dad stated, pull them out a bunch at a time. After which he began wanting by means of them. Then he would hand the papers again to his son.
Shaun Raviv (05:25):
He felt so much like Indiana Jones, looking out by means of some archive with misplaced papers. His son form of checked out a few of the papers. He noticed the stamps that stated categorized on them, however he did not precisely know what was in these papers as a result of his dad did not need him to learn them. He informed him to tug out a metallic rubbish can. He began placing papers in there and he lit all of it on hearth.
Julia Furlan (05:49):
After listening to his story, Shaun realized he wanted to do some severe digging. He knew Woody spent most of his profession educating on the College of Texas. So he thought he’d begin there. Quickly he found a obscure record of papers beneath Woody’s identify saved within the college’s archives. So Shaun determined to ship away for just a few paperwork. What he noticed once they arrived floored him.
Shaun Raviv (06:12):
It was wonderful. It had all these wonderful imagery of individuals’s faces marked up with tons of mathematical equations that I could not even start to know. However there was additionally a whole lot, if not 1000’s of photographs in these papers of individuals with marked up faces, individuals with totally different lights and shadows turning their faces. And quite a lot of these photographs have been in black and white. A few of them have been in shade and so they have been simply lovely. They may very well be artwork.
Julia Furlan (06:39):
Shaun’s subsequent step was to trace down former college students and colleagues who knew Woody again within the early ’60s. That is the place a deeper story started to emerge. A narrative about Woody’s secret profession within the years earlier than he joined the College of Texas.
Shaun Raviv (06:54):
He met a person named Ivan Browning. It is sensible polymath who was simply good in any respect kinds of sciences. Had all these loopy innovations. And so they began engaged on character recognition collectively or automated sample recognition. Attempting to get computer systems to acknowledge patterns. They’re working with letters particularly, however it might work for any written sample or typed sample. It was actually, actually superior. And so they have been efficiently in a position to get laptop to acknowledge letters.
Julia Furlan (07:22):
They understood the importance of the breakthrough straight away. So collectively in 1960, they began an organization referred to as Panoramic Analysis in Palo Alto, California lengthy earlier than it was the tech hub that it’s immediately. Panoramic got down to transfer the world and discover concepts different firms discovered too foolish. They labored on innovations like a robotic lawnmower, a canine powered car, and a pen that might translate mild into sound.
Shaun Raviv (07:50):
So that they have been this group of loopy individuals. They have been simply making an attempt to discover the whole lot. And amongst these issues have been engaged on their sample recognition stuff and so they realized it does not must be simply letter. It does not must be numbers or shapes. It is also faces. He was simply actually large on synthetic intelligence.
Shaun Raviv (08:07):
He gave a speech as soon as and he talked about these visions that he had of computer systems that might do what we do. That might take a look at an individual and let you know who they’re of individuals sporting Google Glass sort glasses. And he simply had these actually superior visions again then.
Julia Furlan (08:25):
The corporate struggled proper out of the gate. Pitch after pitch to large identify firms have been met with a gradual stream of rejection. So with out company contracts, Woody needed to discover one other income to maintain his firm. And that is the place the plot thickens.
Shaun Raviv (08:43):
So I first had this obscure notion that Woody did work for the CIA in one in every of these biographies that one in every of his associates wrote. However I did quite a lot of digging. I digged by means of 39 containers on the College of Texas in Woody’s archives. And so he apparently didn’t burn each reference to his CIA work. Digging by means of all them, it was simply actually clear that a few of these firms that he was getting employed to work for have been CIA entrance firms paying Woody and Panoramic to do facial recognition analysis.
Julia Furlan (09:11):
Woody began by making an attempt to get a pc to acknowledge 10 faces. So he enter the photographs of 10 individuals into the pc after which enter one other 10 footage of the identical individuals to see if the pc might match them. Woody rapidly realized simply how advanced and elusive this know-how could be.
Shaun Raviv (09:34):
There was form of an excessive amount of variability in a face and in a photograph of a face. If you consider it, you’ll be able to take a look at an image of the identical individual, two totally different photographs, and so they look fairly just like us as a result of we’re human. We will see that they’ve the identical nostril, the identical form mouth, the identical eyes, similar hair, however a pc simply cannot instinctually do this.
Shaun Raviv (09:52):
They must get by means of issues just like the lighting within the photograph, shadows within the photograph, the way in which the face is turned, the feelings of the face. Should you’re offended and in the event you’re glad, you simply appear to be a special individual to a pc. You appear to be a special factor, a special form. Nevertheless it was an enormous failure. They weren’t in a position to do it.
Julia Furlan (10:07):
The computer systems of the time simply weren’t highly effective sufficient for the duty. Nonetheless, Woody requested the CIA for cash to proceed his work. And the CIA stated sure. That is when Woody modified ways. For his first try, he tried to make the method utterly automated. This time, he would take what he referred to as a person machine strategy, which might give the pc some human help. The crew started mapping coordinates for various facial options in every photograph, together with the eyes, nostril, and eyebrows.
Shaun Raviv (10:37):
They used this to attempt to acknowledge at first, I take into consideration 50 faces and it labored fairly properly. They tried to cross match a photograph of Woody when he was youthful from 1945 to a photograph of Woody when he was older in 1965, however he seemed completely totally different in these photographs besides to a human.
Shaun Raviv (10:53):
He had misplaced a lot hair, his face and jaws seemed totally different and the pc simply could not acknowledge him. And so total, the second try was rather more profitable than the primary, but additionally nonetheless a failure. The pc could not do what Woody needed it to do.
Julia Furlan (11:10):
By then, Woody had good purpose to look older. His funding was drying up and the stress of his work whereas making an attempt to help his household left him emotionally and financially drained. In 1966, Woody left Panoramic and took a job on the College of Texas. Shortly after, Panoramic went out of enterprise.
Julia Furlan (11:30):
A 12 months later whereas residing in Austin, Woody obtained yet another likelihood to work on facial recognition know-how. He was requested to develop a pc system that will enable legislation enforcement to match mug pictures with photographs of potential criminals. Woody went to work and this time he gave himself a troublesome purpose. He needed his software program to match faces quicker than an individual might, who did it manually.
Shaun Raviv (11:53):
So the quickest human took six hours to complete the duty. However the laptop, which was referred to as a CDC 3800 accomplished the identical process in about three minutes. So it was 100 fold discount in time. So the people have been truly higher at dealing with head rotation and the dangerous photographic high quality of a few of the photographs, however the laptop was actually, actually good, significantly better at seeing the distinction between individuals who had aged. Nevertheless it was actually the best success of Woody’s profession. And it was the final time he ever did an official undertaking on facial recognition
Julia Furlan (12:28):
By 1970, the key nature of Woody’s facial recognition work got here again to hang-out him when a paper about facial recognition know-how was launched by one other researcher. This new analysis was celebrated by Scientific American Journal as probably the most innovative facial recognition know-how of the time.
Julia Furlan (12:44):
However so far as Woody might inform, it was years behind what he had completed at Panoramic. He stated he was pissed off {that a} “second fee examine” could be seen as the very best facial recognition system out there. Sadly for Woody, due to the highest secret nature of his analysis, he could not inform individuals about his work and he by no means obtained the credit score he deserved.
Shaun Raviv (13:04):
None of his facial recognition papers have been printed. And that alone might be proof that he was working for somebody that did not need them printed, however they have been CIA funded papers. And they also simply form of obtained forgotten. They have been disappeared.
Shaun Raviv (13:17):
I used to be capable of finding drafts of them in his containers within the College of Texas. I assume, he was too pleased with them to only destroy all of them. After which his work in facial recognition was utterly forgotten by the point it form of picked up and have become a extremely essential a part of society like it’s immediately.
Julia Furlan (13:36):
When Woody died in 1995, tributes poured in. Pals and colleagues praised his work in arithmetic and his work in automated reasoning. Not one in every of them talked about his groundbreaking work at Panoramic, which is the premise for a lot of the facial recognition tech we’ve immediately.
Julia Furlan (13:52):
It will be one other 25 years earlier than Shaun Raviv’s story in Wired Journal would unfold consciousness of Woody’s work and what it means to immediately’s laptop imaginative and prescient and facial recognition innovators. For Karthik Kannan, Woody’s story was a watch opener.
Karthik Kannan (14:07):
Yeah, I believe it occurs so much with AI pioneers the place they’re engaged on know-how like this, however it’s not one thing that they find yourself getting credit score for as a result of they’re simply forward of their time. After I was studying the article about Woody and the work that he is executed is form of the work that everybody else is constructing on prime of proper now. That is simply how science evolves, I believe.
Julia Furlan (14:29):
Till just lately, Woody Bledsoe was an invisible pioneer in what grew to become a large business. However due to Shaun Raviv, his legacy is now out within the open for all to see. And Karthik’s Envision glasses are the newest chapter in that legacy. The software program works in a brand new technology of Google Glass, which has a tiny digital camera lens embedded within the entrance of the frames.
Karthik Kannan (14:53):
Now, these are the glasses, proper? So I am sporting them. After which I hope you can hear stuff, proper? So now I am simply going to go forward and swipe on the glasses and it simply speaks out all of the totally different classes.
Speaker 2 (15:06):
Learn.
Karthik Kannan (15:06):
There may be learn, for instance, the place you’ll be able to learn textual content.
Speaker 2 (15:09):
Discover.
Karthik Kannan (15:09):
So it is obtained discover. So you have obtained discover individuals, discover objects inside the discover class.
Speaker 2 (15:14):
Determine.
Karthik Kannan (15:15):
There’s additionally determine, which is principally used to determine various kinds of objects round you. It is simply obtained quite a lot of common identification capabilities.
Speaker 2 (15:23):
Describe scene.
Karthik Kannan (15:24):
So I am at describe scene. After which I simply do a two finger double faucet. So you’ll be able to hear it processing.
Speaker 2 (15:34):
A laptop computer on a desk.
Karthik Kannan (15:35):
It stated a laptop computer on a desk.
Julia Furlan (15:40):
Envision glasses are successfully an AI assistant for the blind and visually impaired. They inform the consumer what’s close by, give visible details about an object and the consumer’s setting. And naturally, they acknowledge faces. The enterprise was born in 2015 when Karthik was invited to discuss software program improvement at a college for the blind in India.
Julia Furlan (16:00):
He introduced alongside a pal who’s additionally named Karthik. Karthik Mahadevan. To maintain issues clear, I’ll name his pal Mahadevan. They have been requested about profession paths inside their vocations and what issues they may resolve with our work.
Karthik Kannan (16:12):
And simply as a enjoyable experiment, we determined to throw the query again on the children and we requested them, what sort of issues would they like to unravel? Some individuals stated the textbooks that they’ve or typically the fabric that they arrive throughout of their life, it is changing into actually troublesome for them to learn by means of that stuff. They need to have the ability to resolve it in a roundabout way utilizing know-how.
Karthik Kannan (16:33):
Some individuals stated that they need to have the ability to simply navigate their environments extra independently, know if individuals are coming in the direction of them or know if there’s something in entrance of them. It was a really eye opening dialog. For some purpose, that discuss actually stayed with us. And we felt that there must be one thing that we might do. And we simply began to speak about random concepts.
Julia Furlan (16:59):
Throughout the bus experience house, Karthik and Mahadevan started brainstorming. AI was hitting its stride. New functions have been beginning to be pretty much as good as people at increasingly more duties, together with the flexibility to determine faces. Quickly after, Mahadevan headed to the Netherlands to start out his masters. When he arrived, he wanted a subject for his thesis.
Julia Furlan (17:20):
He thought again to the discuss he and Karthik gave on the faculty for the visually impaired. And after a little bit of deliberation determined to do his thesis on how AI, laptop imaginative and prescient, and facial recognition may very well be used to assist the blind. Karthik was instantly intrigued by his pal’s concept.
Julia Furlan (17:38):
So the 2 determined to crew up with Mahadevan on analysis and Karthik on constructing the app, an app which might serve two distinct capabilities. It will learn textual content and it might acknowledge objects and faces. Karthik’s first day engaged on the undertaking was spent at a Starbucks in Bangalore. From morning till late at evening, he learn research and papers on facial recognition.
Karthik Kannan (18:01):
It was the primary time I keep in mind that I truly took my time to review a human face. I’ve seen a human face and I’ve lived with all of it my life, however it’s the primary time I am noticing, so the space between the eyebrows, for instance, or the size of the nostril, or somebody has a pursed lip. And I nonetheless bear in mind actually zooming into my face and I wrote this little code that put all these crimson dots over my face to essentially perceive the relationships between various things.
Julia Furlan (18:33):
After just a few weeks, Karthik had constructed a crude prototype. It was a white display with a blue button. Press the button and it might take an image with an automatic voice describing what it noticed. On the similar time within the Netherlands, Mahadevan interviewed individuals with visible impairments, asking them to check the prototype and supply suggestions.
Julia Furlan (18:52):
A member of his thesis group shared it with just a few individuals and people individuals rapidly shared it with others. Quickly, the app had a whole lot of beta testers. Immediately, there was a torrent of suggestions permitting Karthik to rapidly refine and enhance the prototype. Finally, Mahadevan reached the tip of his thesis. So the 2 reluctantly determined that it was time to finish the undertaking.
Karthik Kannan (19:14):
I nonetheless bear in mind sitting down and simply composing a really fast e-mail saying, hey, thanks so much for being a part of this journey. It has been tremendous wonderful. And we hit ship. And get up the subsequent morning after which I actually discover my inbox which is 200 replies and it was simply popping. It was like, pong, pong, pong. It was like I might hear the notification on my cellphone all by means of morning.
Karthik Kannan (19:35):
And each one in every of them truly took out the time to jot down some actually considerate stuff. I bear in mind this one notably previous consumer who was like, typically my kinfolk meet up after which my grandkids additionally come. And so what occurs is the mom shares footage of all of the totally different grandkids.
Karthik Kannan (19:51):
And she or he would inform me that each time she shares a photograph on WhatsApp, she simply takes the picture from WhatsApp, places it into the Envision app and she or he is aware of who’s within the image. And the Envision app additionally offers her a caption, appears to be like like so and so wanting on the digital camera and smiling, proper?
Karthik Kannan (20:05):
And so she’s like, swiftly I will truly be a part of the dialog. And there have been tales like this and it virtually felt very troublesome for us to close it down, proper? I believe there was one or two individuals who truly put the thought of us doing this full time and beginning this as an organization.
Julia Furlan (20:27):
Karthik determined to go away India to proceed engaged on Envision with Mahadevan within the Netherlands. There, they ramped up their work. After numerous hours researching, speaking to customers, refining, and bettering, they have been lastly prepared. In late 2018, they launched the Envision app. Two days later and with no promotion in any respect, they’d 4,000 customers. Then got here an e-mail from Google.
Julia Furlan (20:53):
It stated they’d been nominated for a Google Play award. And the nominees have been invited to attend a giant convention in San Francisco the place the winner could be introduced. Envision was up towards some fairly steep competitors, together with one other facial recognition platform that had over 200,000 customers. So Karthik by no means actually gave a lot thought to the award itself. He was extra fascinated with assembly some tech entrepreneurs, seeing some websites, and having fun with California.
Karthik Kannan (21:18):
I nonetheless bear in mind I used to be not that properly dressed for the event. I used to be most likely the worst dressed individual in that room. I bear in mind I used to be simply standing there. I used to be dwell streaming the occasion to the opposite Karthik again right here within the Netherlands. I used to be on a video name with him. I used to be placing it on and I used to be simply exhibiting him, see, Envision’s brand is developing there.
Karthik Kannan (21:36):
And the subsequent factor they are saying is the Google Play award, the winner is Envision. And I begin to freak out as a result of then I am like, wait did we actually win it? After which I might hear all these expletives coming from the opposite facet of the video name. After which I reduce the decision. I walked up the stage.
Julia Furlan (21:51):
The contacts Karthik made on the convention paid off. When Google introduced they might launch a brand new version of Google Glass in 2019, Karthik persuaded them to ship him a pair earlier than they hit the market. Incorporating their facial recognition software program right into a wearable was the subsequent logical evolution for the corporate.
Julia Furlan (22:11):
And it seems Google Glass was precisely the {hardware} Karthik and his crew wanted to take their subsequent step. Right now, between the app and the glasses Envision is making the world extra accessible for 40,000 individuals who use their know-how. It is serving to every of them dwell a extra impartial life and expertise the world in a method Woody Bledsoe hoped would possibly in the future be potential.
Julia Furlan (22:42):
Since its ominous beginnings as a secret CIA funded undertaking, laptop imaginative and prescient and facial recognition have impressed controversy. There’s actually no scarcity of problematic functions that convey up essential questions round issues like privateness and surveillance. And that will not go away anytime quickly. However Shaun Raviv reminds us that no know-how is inherently good or dangerous. It is what we do with it that actually issues.
Shaun Raviv (23:05):
Facial recognition know-how is, indisputably, some of the horrifying applied sciences on earth. It will also be a extremely helpful know-how and has been. And my hope is that it is solely used for good issues sooner or later. And issues like serving to the blind see is a kind of optimistic issues.
Julia Furlan (23:21):
For Karthik Kannan, the last word purpose is similar because it was when Woody Bledsoe first began engaged on facial recognition again within the ’60s, to in the future construct one thing that may acknowledge the subtleties of the human face with the convenience and pace of our personal thoughts. And Karthik believes that when that day arrives, the individuals who will profit probably the most are the individuals he is already serving to immediately.
Karthik Kannan (23:45):
We’re simply slowly scratching the floor of it. We understand that 90% of the knowledge is visible and there is so many visible relationships that the mind is ready to kind in a fraction of a second. And that visible constancy is what we finally wish to seize with AI. So AI, in that sense, is the right match for serving to visually impaired individuals as a result of AI is a instrument that does not count on the world round it to vary. It takes the world as it’s. And it actually tries to interpret it in a method that may assist visually impaired individuals.
