I had this one bookmarked since my playing with Google Similar Images Search. Waited for occasion to post about it, but none came. So here is post without occasion.
TinEye is image search engine that takes image and looks for its online copies and derivatives.
What it does
TinEye takes uploaded image, or link to one online, as input and searches index for other images (parts of images) that have similar fingerprint, as they call it. It doesn’t work well with small or overly simple images, there has to be enough details to process.
Their index currently holds over billion images. May not be considerable chunk of Internet but still lots and lots of pictures.
- very precise matches;
- quick comparison between query and found matches;
- sort by dimensions makes easy to look for same image in better quality;
- bookmarklet and browser plugins.
While TinEye site itself may seem like one of those online toys without much practical purpose, in reality technology that powers it goes beyond search fun.
TinEye itself seems to be work in progress with gradual addition of features and upcoming API.
Service is quite unique in what it offers. I might not need something like this often, but this is seriously cool tech and I look forward to future improvements and products.
