Has any work been done in partial image recognition with fault tolerance?

I realize my title might not explain my needs as best as it could, however I lack the knowledge to better name my needs at this moment. My apologies.

Basically, I'm wondering whether there are any tools or APIs (for AutoIT) that I can input a part of an image, and make it search this part's location inside another image. If a perfect match is not found, I would like to be able to enter a certain offset percentage (there should be a better name for this). Meaning that a slight difference is colors or the amount of pixels matching would not be a problem if it is within a given margin.

Has anything like this been done before? Any feedback is appreciated.

Thanks.

Search the forum for "ImageMagick", it has a compare function where you can specify a fuzz factor.

Looks interesting, but what command makes it search for an image in another image?

Use the -subimage-search option.
