Face Contour Detection Using Geometric Active Contours

摘要

In this paper, a new method that incorporates prior shape information into geometric active contours for face contour detection is proposed. The improved geometric active contour model is implemented using variational level set approach. With this model, face contours in images with complex backgrounds can be detected accurately depending on both the image edges and the prior face shape. The experiment results show the efficiency and effectiveness of our method.
