Using the basic method of learning

Using the basic method of learning digital image processing, the texture characteristics of the fabric must be represented by a structured image. Feature extraction is the basic concept of computer vision and image processing, using a computer to extract the basic information of the collected image and check that each image point extracted from the computer belongs to the image function. The result of feature extraction is to divide the extracted points into different subsets, which are often isolated points, continuous curves, or continuous regions [8]. Extracting image features can be divided into two levels. One layer is the extraction of the lowest layer feature and the other layer is the extraction of the upper layer feature.
