摘要: Finding faces, locating important facial features and model fitting are required in a range of applications including based multimedia coding. Accurate lip is essential where to be fitted head shoulder colour image. Existing approaches include deformable templates active contours. An contour using combined balloon pressure image gradient snake with adaptive thresholding for improved accuracy described. Results from applying this technique large database images (XM2VTS) well known sequences presented. These demonstrate high success rate satisfactory fitting. Examples animations the automatically faces also included.
