ABSTRACT:
In a fingerprint/palmprint image processing system and method, for local regions other than a highly reliable region, a ridge line image which can be estimated to represent a ridge line is selected from ridge line candidate images, and whether or not each of the selected ridge line images is valid as an image representing a ridge line is discriminated. Thus, a whole image is generated on the basis of the ridge line image in the highly reliable region and the ridge line images which were discriminated to be valid in the other regions.
