We propose a method of fabric surface imaging and processing so that information about wrinkles can be extracted and evaluated. We consider two images of the sample obtained under orthogonal lateral illumination and apply a joint Canny edge detector to integrate the information about wrinkles of both images. The smoothed and scaled perception of wrinkle edges with the viewing distance and its influence in the evaluation of the fabric appearance is simulated, analyzed and proposed for a more realistic assessment of a fabric.
