Research on Key Technology in Construction of a Chinese 3D Face Database

By acquiring the human faces through the CyberWare 3D scanner, a Chinese 3D colo r face database is constructed. To build 3D face database, the original 3D data should be preprocessed, and the 3D faces should be standardized in a uniform for mat. The key to the problem of standardization is the pixel-to-pixel alignments among the 3D faces, which is a difficult problem in computer graphics and comput er vision. Generally, the optical flow algorithm is used for the alignments, but the result is not so good. To get precise alignments of the 3D faces, a method based on resample algorithm is proposed. The experimental result shows the metho d is feasible.
