Abstract
In this thesis, we present a system for face replacement in video. Our approach is based on 3D morphable model, so the input is reduced to one or two pictures for the source face to be placed in. Then, we can replace the target face in the target video with the source face, under similar pose, expression, and illumination.ost digital processing software can perform image face replacement only when the poses for the source and target faces are similar, and the manipulation process with those software is often time-consuming and labor-intensive. While most previous work also focuses on image face replacement, our system performs face replacement in video. Our system is useful in the special effect industries and entertainment.ur system consists of several modules: face alignment, pose estimation, expression estimation, face extraction, morphable model fitting, face synthesis, lighting estimation, and composition. In this thesis, we focus on pose and lighting estimation.
