How to detect occurrencies of a small image in a larger image?

Question

I would like to detect the occurrencies of a small image in a larger image, as well as coordinates.

How do I do it with C#/.NET?

Answer 1

An extremely low-level way to do it would be to read in the file as a bitmap stream (assuming you can convert it to bitmap) and parse it to search for patterns. But your algorithm would have to be very, very refined. So basically, what P.Brian.Mackey said.
