This may look like a fail at first glance. And ultimately, I suppose it is. But I'm still pretty impressed. Let me tell you why.
So if you didn't know, the new Google Photos offers a pattern matching feature of some kind. You can search for things or people in your photo library. The face matching especially is absolutely astounding. Note that it doesn't attempt to identify people, only group together photos containing the same face. No matter how tiny that face is, or how blurry. Sure, there's some false positives and false negatives. But I'll bet that, in most cases, Google will do a better job finding all the pictures containing a face than the owner of those pictures would. Searching for things is also highly impressive. It gives you several suggestions right up front for things it's found already in your library, and it was in browsing those that I found this picture...under "dogs".
So nearly all results were in fact dogs, or at least very fat cats. This picture however is a strange one. It's a door. But if you look closely, and if you have played Minecraft, you may notice something else. There is actually an animal in this picture: a chicken. Its beak is sticking out of the door due to the curious physics of the game. Now, I don't know if the algorithm saw the Minecraft animal, or if it thought it was a dog door, or something else entirely, but I would not have caught that at all, even under the criteria "animal". So, yes, it's kind of a fail, because this isn't a dog, but it's still a pretty cool fail.
I for one welcome our Google AI overlords :)
