The tissue properties of the fabric

The tissue properties of the fabric mainly have aspects such as roughness, structural properties, periodicity, directionality, and continuity. In the automatic detection of fabric defects, the gray scale of the fabric texture image is often used together with the statistical characteristics, and it is judged whether a defect exists after comparing with the fabric texture characteristics [24]. In this white paper, we mainly select four unique values ​​that are easy to calculate, easy to implement, and have good effects such as entropy, energy, extreme values, and variance. Set it to a gray value at the pixel point of the image, M is the number of rows in the image, N is the number of columns in the image, and the average value of the gray values ​​in the image.
