Application of Improved ASM and AAM Fusion in Face Tracking

Based on the active shape model(ASM) and active appearance model(AAM) algorithm, using the AAM texture matching for global search and ASM feature points localization of local search, a new algorithm that combining the characteristics of both is adopted. This algorithm ensures the accuracy of feature point positioning and enhanced the texture matching accuracy, improved the tracking accuracy and quickness when target partially obscured and nearby background change in the process of face tracking effectively. Experimental results show that the algorithm improved the precision and robustness greatly.
