METHOD FOR DISTINGUISHING FRESH MEAT FROM MEAT SUBJECTED TO FREEZING BY MEANS OF ANALYSIS OF IMAGES OF MUSCLE TISSUE AND CORRESPONDING SYSTEM ARRANGED TO EXECUTE SAID METHOD

摘要

A method is described for distinguishing fresh meat from meat subjected to freezing, comprising an acquisition step (900) of at least one image of the muscle tissue sample, a step (1000) of generating at least one counting matrix of the occurrences of colours of the pixels that make up the image, a step (1100) of quantization of the image pixel colours, a step (1200) of converting the acquired image into a reduced colour image, a step (1300) of recognition of vacuoles in the reduced colour image, a comparison step (1400), in which the number of vacuoles (10) recognised is compared with a threshold, determining that the sample of muscle tissue has been frozen if the comparison step determines that the number of vacuoles (10) recognised is greater than the threshold, and determining that the sample of muscle tissue has not been frozen if the comparison step determines that the number of vacuoles (10) recognised is smaller than the threshold.
