Abstract: Marbling level of beef rib-eye region is one of the important indicators in beef classification. A total of 50 rib-eye images were taken by using industrial cameras, then VC++ image processing technology was used to denoise image through smoothing operation; then the rib-eye region was isolated from background with adaptive threshold before the effective rib-eye region was determined by using mathematical and segmentation-based method. Eventually we could identify marbling through mathematical statistics method. Experimental results show that machine vision can effectively identify rib-eye region of the marbling, and its short time-consuming and accurate identification will help determine the exact quality level of beef.

Key words: beef rib-eye, marbling, erosion, dilation, image segmentation, recognition
