摘　　要：为了提高主动形状模型（ASM）算法的性能，提出了从ASM模型的初始位置、人脸特征点局部搜索两方面改进的叠加ASM模型及局部特征点搜索的二维轮廓线算法。实验结果表明，该算法比传统的ASM对人脸面部特征点定位有更高的精确度。To improve the performance of active shape model（hSM）algorithm, the stack ASM model and two-dimensional contour lines feature points of local search algorithms are introduced by improving the initiai position of the ASM model and the facial feature points of local search strategies. Experimental results show that our algorithm performs significantly better than the traditional ASM.
