To model the lip moving of Chinese speech with fewer features, this paper presents a feature extraction method that bases on the quadratic interpolation of inner lip contours. The most difficult task of applying inner contours to represent lips is the removing of teeth effects. To address this problem, this paper firstly maps the color space into chromatic color space, which can decrease the effect of teeth and paves the way for extracting the inner lip. In order to get correct lip contour, an… CONTINUE READING
