Abstract: To realize the fabric seam in calendaring process, a detection method is proposed to recognize the seam of image based on digital image processing. Taking down-proof fabric in calendaring process as example, the down-proof fabric images are processed into gray image and filtered with a median kernel firstly; and then the mean value, standard value and coefficient of variation (CV value) are extracted as the feature parameters; by comparing and analyzing the three feature parameters, CV value can be used to recognize the seam of fabric image at last. The experimental results show that the CV value is better suited to recognize the fabric seam which has a small amount of calculation with a high detection rate.
