基于ASM的人脸面部特征定位算法的改进

Abstract

Abstract:

This paper makes several improvements of traditional active shape model for face orientation.It is hard for the conventional ASM to match accurately on each landmark;what's more,the trained model depends heavily on the clutter background.In view of the drawbacks mentioned above,firstly,we propose the local texture model in clutter background;secondly,we design the 2-D model for corner points;and lastly,we add fringe restrain in the model of partial grey level,so that the points with strong fringe information could have more possibility to become the perfect candidate points.Experiment results show that the improved algorithm is superior to those available in accuracy and robustness.

Key words: face recognition;face alignment;active shape model
