Vision-Based Lip Contour Extraction and Tracking for Generating MPEG-4 Facial Animation Parameters

碩士 === 國立東華大學 === 資訊工程學系 === 94 === We propose a method for extracting lip contour using deformable templates controlled by quadratic polynomials. The proposed method combines color, shape and motion cues to estimate the contours of the outer lips. An error function is designed for merging these cue...

The proposed method combines color, shape and motion cues to estimate the contours of the outer lips. An error function is designed for merging these cues and a hill-climbing algorithm is applied to obtain the parameters that minimize the error function. In addition, the movements of the feature points around the lip contour are extracted based on the specification of the MPEG-4 facial animation parameters. Then the extracted parameters can be used to synthesize and animate a virtual face. Mau-Tsuen Yang 楊茂村 2006 學位論文 ; thesis 34 zh-TW
