该模型首先根据人耳的几何特征对人耳进行粗分类；然后应用独立分量分析的方法提取代数特征，支持向量机进行细分类，最后给出分类结果。

• The model made rough classification to the human ears first according to their geometric features, then ICA was used to extract the algebra features and support vector machine (SVM) was for detailed classification, finally the results were achieved, which was in accordance with human natural recognition process.
