“…Visual standards grade the marbling in seven scores by the National Pork Board (NPB, 1999). Some research works were reported for assessing beef or pork marbling by machine vision (Faucitano, Huff, Teuscher, Gariepy, & Wegner, 2005;Shiranita, Hayashi, Otsubo, Miyajima, & Takiyama, 2000;Tan, 2004;Toraichi et al, 2002;Yoshikawa et al, 2000).
