AUTOMATED 3D-2D PROJECTIVE REGISTRATION OF HUMAN FACIAL IMAGES USING EDGE FEATURES

摘要

In this paper, we describe a method of automatic 3D-2D projective registration between the 3D (i.e. polygonal face surface derived from CT or MRI data) and the 2D faces of the same individual in the photographs. Our task is to make a realistic 3D model face for post-surgical simulation by pasting color textures accurately on the face surface. We utilize edge features such as external edge (facial outline) and internal edges like eye, nose and mouth edges from both the 3D face and photographs for matching. We define 3D edge as a set of 3D surface points which is 2D edge on the projected space.
