Comprehensive evaluation of appearance quality of fabrics based on image analysis

Since 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,which can use precise digital data to describe and evaluate the appearance quality of fabrics.The appearance quality of fabric is described by constructing five gray features—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 the appearance quality of fabrics and provides a new concept for objective and standardized evaluation of fabric appearance quality.
