Fingerprint-Recognition

Subimage.m is a MATLAB function that extracts a part of the image specified by its parameters. The image should be a binary image (e.g. not color image).Function elements: f-binary image m,n-dimension of extracted image rx,cy- starting point of f from which the cropping starts.
