Abstract

We present an automatic lip contour extraction and tracking method based on an improved active contour model, which introduces a novel image gradient detection based on the segmented lip, tongue and oral cavity image obtained using a nonlinear transformation of the YCbCr color space and a novel entropy analysis based segmentation. The proposed method provides encouraging results with different mouth shapes (with the appearance of teeth, tongue and oral cavity) under various illuminations.
