How does reverse image searching work
In: 1
Say I’m the reverse image software, and I’m tasked to identify a mysterious object (it’s a banana). I have billions upon billions of other already identified images by humans, on the internet. To identify this I compare it to visually similar pre-identified objects. I then use these labeled images to describe this object, and then I ask the internet. I see that it’s yellow. I see that it’s in a crescent shape. I also see that it has brown tips. When I compare it to labeled similar pictures, I see people eating it. I then see visually similar objects with it in many photos, labeled fruits. Now I ask the Internet: Edible yellow crescent-shaped fruit with brown ends. Lots of sources say it’s a banana. I search for banana photos and compare them. This mysterious object is a banana. I then label the photo and add it to my collection, for later identification.
