The model was preprocessed to assure the regulation of facets, create the dual graph of it, and then adapt Reeb Graph to extract the skeleton which contains enough information of the model, such as gesture and topological features, to be able to be used as descriptor of 3D model retrieval.

通过对模型进行一定的预处理保证面片的规则，定义面片间距离计算方法，创建模型的对偶图，识别连通分量，在连通分量上应用Reeb图的计算思想抽取原模型的骨架。试验表明，该算法具有较好的计算效果和效率，最终的骨架保存了模型的拓扑连通性以及姿态，可用于基于内容的三维模型检索时的特征描述符。

According to the Marr's visual theory, a novel face image presentation model, dual attribute graph , is put forward in the thesis. Each node of the graph has two attributes, local principal component coefficient and Gabor coefficient. So the presentation of face image can be converted from gray level to more high level.

根据Marr的视觉表示理论，本文提出了新的人脸图象表示形式---双属性图表示，属性图中每个节点有两个属性特征，局部主成分系数特征以及Gabor系数特征；从而将人脸图象的灰度级表示，转化为更高一级表示。
