| 摘 要： | 在主动形状模型基础上,借助于核的技巧,对其前期所需的广义对齐算法进行了研究改进,使之能够在后续的主分量分析中更迅速有效地捕捉不同的面部形状变化,进而达到快速定位面部关键特征点的目的.实验结果表明,改进的算法在主分量分析之后能够更好地表达不同脸形变化的模式,而且在定位面部关键特征点上精度更高,收敛速度也有明显改善.

| Abstract: | This paper presents a new method to align the facial feature points,which is developed from the generalized procrustes analysis,and improved by adding nonlinear information of facial points and using the active shape model and the kernel trick.Experiments show that the improved method has better performances in obtaining more detailed modes of face shape and better accuracy in searching unknown target image points.Meanwhile less time is spent for the search. |
