Abstract:
A method of sending a facial image comprising the steps of:using a set of multiscale templates locating a point on said facial image with the highest correlation coefficient at the best scale as the location of the face;detecting facial features by template matching facial features to provide a set of points defining said facial feature locations;encoding said facial image into eigenface parameters including the steps of providing a training database of eigenfaces and performing eigenface decomposition of an input image by finding eigenvectors and eigenvalues of points in free space represented by a training set of images;transmitting and receiving said eigenvalues and said set of points defining said facial feature locations;providing at a receiver a three-dimensional generic model of a face;warping said generic face model using said set of points defining said facial feature locations;said warping step includes using an affine transform for a portion of said face and bilinear transform to warp a different portion of said face;decoding said facial image from eigenvalues to reconstruct the face image to define a texture image;said decoding including the step of providing said training database of eigenfaces; andmapping said texture image onto said warped three-dimensional face model to provide a synthesized facial image.
