fast finding of small image in a bigger image
I need to get the coordinates of a small image location residing in a big image (let say I need to search for a specific tree inside a forest photograph. If the sub-image is found then the result would be something like: x=120 y=354 by example).

Is there a fast algorithm that I could use ?

I'm using Delphi (can also use Java if needed)

Thanks in advance
