Abstract :
Active shape models (ASM) is one of powerful tools for feature extraction. A new method to construct local appearance model is developed using the information of neighbor landmark points in this paper. This improved method is evaluated on ORL face database, and the experimental results show that the improved ASM improves the accuracy of features extraction.
