ABSTRACT:
Fabric wrinkles are automatically evaluated using a reliable, accurate, affordable, and efficient system. Two algorithms are used, the facet model algorithm and the plane-cutting algorithm, to extract features for evaluating wrinkles in fabrics. These algorithms eliminate the need for independent evaluation of a fabric specimen by a technician.
