    The present of grading leather quality by human eyes is not reliable. Because inconsistency of grading due to eyes strain for long time can cause incorrect result of grading. Therefore it is necessary to automate the process of grading quality of leather based on objective standard for it. In this paper, We suggest leather automatic classification system consists of the process obtaining the information of leather and the process grading the quality of leather from the information. Leather is graded by its information such as texture density, types and distribution of defects. This paper suggests the algorithm which sorts out leather information like texture density and defects from the gray-level images obtained by digital camera. the density information is sorted out by the distribution value of Fourier spectrum calculated from frequency domain. And the defect information is obtained by the statistics of pixels which is relevant to window using searching window after sorting out boundary lines from preprocessed images. The information for entire leather is used for standard of grading leather quality, and the proposed algorithm would be practically applied for machine vision system.
