摘　　要：研究一种基于图像处理技术的牛肉大理石花纹自动等级评定方法。通过图像重采样、单阈值分割、形态学腐蚀及膨胀等方法分割出大理石花纹,再提取图像的特征参数组,并用多元回归分析的方法构造牛肉大理石花纹评级模型,并用VC++实现了自动评级软件。通过对多个牛肉图像的检测,表明此评级计算模型具有良好的准确性和鲁棒性。Beef marbling is the most important parameter of carcass grading and beef marbling grading is based on the measurement of fat density in the muscle of eye area.An automatic beef marbling grading technology was explored based on image processing.Imaging acquisition,single threshold segmentation,morphological erosion and expansion were used to extract feature parameters of images.Multiple regression analysis method was used to classify beef marbling structure and the final grading evaluation was implemented using an automatic grading software developed based on VC＋＋.Our grading model had good accuracy and robustness.
