Abstract: Aiming at the result of subjective evaluation of fabric appearance quality is not exact enough at present, this paper proposes an analysis method based on image gray. This method can use precise digital to describe and evaluate the appearance quality of fabric. The appearance quality of fabric is described by constructing five gray features that are gray range, texture evenness, energy range, contrast range and roughness range. An evaluation method based on magnitude adjustment and variable weight that can comprehensively calculate five features and form evaluating index is given. Experiments and analysis show that this method can reasonably describe and evaluate appearance quality of fabric and can provide a new research thought for objectification and standardization evaluation of fabric appearance quality.
