Grading System of the Meat Freshness Based on Plaque Characteristics

Based on mathematical morphology method, the paper analyzed and calculated plaque area in the image of plaque bacteria though taking Hough transform to extract complete outline of fat cells. TVB-N values in the process of pork Corruption is taken for a sequence of inputs of SOM neural network used for the cluster analysis of TVB-N values and dividing pork freshness to five classes. Complying with national standard and sensory test results, it achieve the results of the test to class the pork freshness.
