(3) And texture defects, namely, extracting the torsion degree, kurtosis, energy and entropy six-dimensional gray level histogram statistical characteristics of the gray level mean value gray level variance from the characteristics of the gray level histogram. The gray histogram is a probability statistic of the pixel distribution of a number of different gray levels in an image. Assuming that a sample of an image has 256 gray levels (whose gray value i is 0,1,2,3, …,255) and the total number of pixels of the gray level i is N, the probability of the gray level i is p (i)/N, and p (i) at each gray level is counted to construct a first-order gray histogram of the image, and then a standard of the gray histogram in the region is set.
