Abstract: In this work, we develop a multi-scale approach for automatic facial feature detection and tracking. The method is based on a coarse to fine paradigm to characterize a set of facial fiducial points using a bank of Gabor filters that have interesting properties such as directionality, scalability and hierarchy. When the first face image is captured, a trained grid is used on the coarsest level to estimate a rough position for each facial feature. Afterward, a refinement stage is performed from the coarsest to the finest (original) image level to get accurate positions. These are then tracked over the subsequent frames using a modification of a fast phase– based technique. This includes a redefinition of the confidence measure and introduces a conditional disparity estimation procedure. Experimental results show that facial features can be localized with high accuracy and that their tracking can be kept during long periods of free head motion.
