Abstract

A fabric image of RGB is transformed into an HLS image and about one half of a stitch is cut out. Autoregression analysis on lightness is performed along the width direction of a thread, the part of a stitch is determined from variation of autoregression coefficient and then hue is corrected for a part of bottom and a part of highlight. Influence of mirror surface reflection light is corrected, and original color of the fabric can be determined.
