Abstract: Features representing count and area densities of marbling were extracted from the marbling images. The linear model including sum marbling area, large marbling flecks density, middle marbling flecks density, and marbling distribution was made to predict marbling grade (R2=0.8415). Based on the prediction model and statistical data of features of marbling image, marbling grade was adjusted from four-point to seven-point rating scales. Sum marbling area from 1 to 7 point was 14%, 11%, 8%, 6%, 4%, 2%, 0.5% of the ribeye area, respectively.
