基于嘴角约束的嘴部轮廓检测

ue to the diversity of the mouth contours in face, The traditional mouth contour detection method based on ASM is not effective,this paper proposes a mouth contour method, Firstly, we use MeanShift clustering to processed mouth grayscale image, and get the location of the mouth corners, then under the constraint of the mouth corners ,we using the traditional mouth contour detection method based on ASM to detect mouth contour. The method has high accuracy to different mouth. Compared with the traditional mouth contour detection method this method has more applicability and robustness.
