I am doing a project about the recognition of the serial numbers in bank notes. After I finished the gray scale normalization of the image, I don't know how to extract the serial numbers from the image. Also, I need to extract the features of each character for the comparing with the serial numbers. However, may I know if there any methods to do this extraction. Thank you very much and Happy new year.

Thank you. Now I have another question. May I know how to make the bitmap figure in the tempalte( characters file)? I try to make the new temaplates by copying the bitmap figure after the program cut the [42 24] character out, but I cannot only cut out the character out without the blackground. May I know if I am right to do these procedures to extract the template figure??

An image must remain rectangular, so you'll need to have both white foreground pixels (representing the M) and the black background pixels. If you want, you can use find() to get a list of the rows and columns where the white pixels reside, but that's just a list of coordinates, not an image.
