Bitmap (of a signature) comparison in c#
We have a for fun project which require us to compare two black and white bitmaps of two signature and say whether they are the same persons signature.  As this is just two loaded bitmaps rather than data captured from a tablet the approach is going to be a little different to normal signature recognition.

I am thinking it would require the following steps

- Crop the bitmaps to just the signature
- Try to work out some kind of rotation to align them
- Resize to make the cropped / rotated bitmaps the same
- Analyse the signature inside (maybe by breaking down into a grid)

Does anyone have any thoughts on this project?  How to best do the rotation, comparison etc?  Seen anything similar?
