Estimating marbling score in live cattle from ultrasound images using pattern recognition and neural network procedures.

Neural network processing of texture statistics (which parameterized longissimus muscle echograms of live cattle) resulted in marbling estimates that differed from corresponding USDA carcass marbling scores by an average of .42 marbling score units. This was more accurate (P < .001) than using the same features in a multiple regression model. Images were… CONTINUE READING
