I use Google Image Search alot, normally to find an image of something quickly or to see what a person, car, item etc looks like. The new Similar Image search is a step in the right direction, although there are alot of things they could do to improve it.
I would love to find out if they’re comparing the images or if they’re comparing the surrounding META data? Or is it a combination of both? I don’t think its based purely on the image, because occasionally a false positive shows up that doesn’t match the other images at all.
The similar image search is a step in the right direction, but I think they could improve the image search function alot more. It would be cool if I could upload my own image for them to search for, but of course the problem with that is if they’re using the surrounding meta data the uploaded image wouldn’t have that.
