The Algorithm and the System The model-based coding technique uses some knowledge of facial structure to recognize and to synthesize images. First, fitting algorithm uses a polygonal wireframe model and input source image to obtain a 3D face model. This 3D face model uses rules to obtain synthesized 3D face model. Then, a 2D source image is mapped onto the new synthe- sized 3D face model by texture-mapping of the composite of the image. In this way, a 3D computerized face is created We discuss a new image synthesis system which can gen- erate facial expressions and aging effects on facial images for a personal computer (PC). This system has wide applica- tions in many areas such as simulation in beauty parlors and cosmetic surgery clinics and montage systems for criminal investigation.
