There are a lot of algorithms talking about how to detect similar images. Is there any actual implementation in any language (but preferably in C/C++) that detects s开发者_JAVA技巧imilar images?

I personally haven't used this library, but you might want to check out OpenCV. It seems to be a very good open-source image library and is supported in C++, C, Python, and soon Java.

Also, this looks like a function that you might want to check out for image similarity if you choose to go with this library.

Hope you find what you're looking for.

Opencv is a good toolkit - but there isn't a single solution because it depends what you mean by the same image.

Do you want to find resized / rescaled / rotated copies of the same same image? in which case a colour histogram is probably a good approach

Or do you want to find different pictures of the same object? In which case you need a feature / line extraction and some sort of matching criterion
