Using curvature estimation of 3d mesh, the method completes the segmentation of face model u-sing interactive makers as indicators. The result is more suited to reality of the human face organ segmentation. The experiment shows that the method is simple, easy to implement and good results are gained.%采用对三维网格的曲率估计，由用户交互提供分割的指示标记，完成人脸模型网格曲面分割。分割结果更符合对人脸模型的器官分割要求，实验证明分割过程快速，方法简单、容易实现，且取得较好的结果。
