How Apple’s duplicate picture detection works

Duplicate detection was a nuanced laptop science downside Apple engineers needed to resolve. I had the chance to talk with one of many engineers that labored on this function final summer season.

Duplicate detection can’t simply evaluate superficial knowledge like file dimension or decision — it must examine when you’ve got each a full-quality and a lower-quality copy of the identical picture. Plus, it wants to determine should you’ve made edits to a duplicate of a photograph, and decide which one you would possibly wish to maintain.

The power to delete duplicate photographs was needed for Apple to correctly implement iCloud Shared Photograph Library (a function I totally suggest trying into for households and shut pals). My spouse and I turned on our shared library, however after all, each of our private libraries have been suffering from the identical photos we despatched to one another within the years earlier than this function.

With duplicate detection, I’m assured that our new unified library doesn’t include 12 copies of that one image of our canine we each like, or two full units of all our marriage ceremony photographs taking over area.
