The invention belongs to the fields of digital image processing and pattern recognition, and particularly relates to an extraction method of the filtration detail characteristics of a Sobel operator for presenting fabric grain. The method comprises the following steps of: firstly, respectively solving transversal and longitudinal basic cycle period span of a fabric image by adopting one-dimensional fast Fourier transformation; then, respectively carrying out horizontal and vertical Sobel operator filtration treatment on the fabric image; and calculating four extreme gray statistics as the detail characteristics on the basis according to the basic cycle period span of the fabric grain and a traversal method principle. Accordingly, the four extracted characteristics respectively present thetransversal edge maximum statistical information, the transversal edge minimum statistical information, longitudinal edge maximum statistical information and longitudinal edge minimum statistical information of the grain so that the characteristic vectors formed by the four characteristics can fully present the details of the fabric grain and have mutual obvious complementarity. The invention avoids implementing binary processing to the image after the Sobel operator filtration and keeps richer usable information of the filtered image.
