| 摘 要： | 由于人耳识别具有不受表情、化妆等影响的独特优势,研究了人耳识别特征技术,对不变矩算法进行了改进,获得6个改进的高阶不变矩特征向量.分别用两种算法对人耳图像进行识别处理,比较两种识别结果.改进后不变矩算法的高阶不变矩具有平移、旋转不变和尺度缩放不变的特性.采用BP人工神经网络对60只人耳图像进行识别验证,正确识别率达到91.8%.

| Abstract: | This paper introduces the process of ear identification.An improvement in moment invariants algorithm allows six feature vectors to be distilled by the method of high-order moment invariants.The use of these two kinds of algorithms in ear identification finds that the high-order moment invariants in the improved algorithm shows the feature of invariance in translation,rotation and scale change.The application of a BP artificial neutral network to identify 60 ear images shows an identification accuracy of 91... |
