ASM and Improved Algorithm for Facial Feature Location

To improve active shape model （ASM） accuracy in facial feature points location in facial images,an improved ASM based algorithm is proposed.First,the irises are localized and utilized to initialize the shape model；Second,facial similar configuration,feature subspaces of global face shape model and salient feature local shape models are all employed to constrain the movement of feature points；at last,logGabor coefficients are used to describe the local texture distribution and build models for each feature point to increase the robustness to illumination change and other noises. Experimental results show that our algorithm performs significantly better than the traditional ASM.
