Does anyone know of a .NET programmable/usable API for reading an image file, and comparing it to an existing set of images? e.g. I have three pictures of the letters A, B, and C. I then copy the picture of A, and modify it so that it is flipped 180 degrees. I'd like to be able to have a piece of software that detects that it is a mat...
