Objective To develop an objective, accurate and nondestructive intelligent grading method of beef marbling based on deep learning. Methods The image recognition method based on deep learning algorithm was used for feature extraction and classification of beef marbling, and the corresponding debugging and learning was carries out. Results The accuracy rates of beef marbling grading reached to 84.2% for the first level, 89.4% for the second level, 81.9% for the third level, 84.1% for the forth level and 82.6% for the fifth level, respectively, through the computer debugging and learning. The recognition rates of beef at all levels were above 80%, the recognition time was all within 1 s, and the desired goal was achieved. Conclusion The image recognition method based on deep learning algorithm can be used for feature extraction and classification of beef marbling, and the accuracy of this method is good. With the increasing number of samples in the picture database, the accuracy of its recognition will be improved continuously, and this method can be widely used.
