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.

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.
