ABSTRACT:
A skin pattern classification system extracts ridge line data and valley line data from image data of a skin pattern. Minutiae are extracted from the ridge line data and the valley line data. Subsequently, minutia correspondence information is obtained by detecting mutual correspondence among the minutiae from the ridge line data, valley line data and the minutiae. Skin patterns are obtained by finding and tracing characteristic lines referring to the minutia correspondence information, the ridge line data and the valley line data, and the characteristic lines and the minutia correspondence information serve to provide pattern classification.
