Abstract: According to the trend of foreign countries and actual research status，automatic beef grading is a new study subject after Beef Grading Standard published in China. In comparison with advanced techniques abroad, the research of automatic beef grading in China is developing. The research advances of automatic beef grading technology aborad and at home were reviewed. To construct an applied system of beef grading with computer vision, researchers in China should combine beef production and signal acquiring with beef edible quality. Separating the marbling texture as one of the important technologies in beef grading does not only meet the present standard, but also meet the standards of the foreign countries.
