Improved level set method for lip contour detection

Abstract

The lip contour detection is essential in many applications such as personal identification, facial expressions classification, man-machine interaction, and so on. In this paper, we propose a new level set approach to detect the lip contour. The approach optimizes the gradient information and enhances the accuracy of the lip contour detection by combining… (More)
