难道你们知道的，可用于计算图像之间的差异的任何算法？

Do you guys know of any algorithms that can be used to compute difference between images?

拿这个网页例如 http://tineye.com/ 你给它​​一个链接或上传图片，并发现similiar图像。我怀疑这比较形象的问题，对所有的人（或者它）。

Take this webpage for example http://tineye.com/ You give it a link or upload an image and it finds similiar images. I doubt that it compares the image in question against all of them (or maybe it does).

通过计算我的意思是像什么 Levenshtein_distance 或的
