Fingerprint skeletonization, also referred to as thinning, is the process of reducing the width of binarized ridgelines to 1 pixel. Standard thinning algorithms are applicable. Modified methods based on local ridge orientation have been proposed to improve skeletonization accuracy. Post-processing for skeleton image, such as skeleton adjustment, is also important.
