Abstract

In this paper, we present a face alignment system to deal with various poses and expressions. In addition to global shape model, we use component shape model such as mouth shape model, contour shape model in addition to global shape model to achieve more powerful representation for face components under complex pose and expression variations. Different from 1-D profile texture feature in classical ASM, we use 2-D local texture feature for more accuracy, and in order to achieve high robustness and fast speed it is represented by Haar-wavelet features as in [5]. Extensive experiments are reported to show its effectiveness.
