Recently, analysis of facial morphology and its relationship to genes has received considerable attention. In this paper, we present a scheme of 3D shape alignment for the morphological study of human face. We employ the Cylindrical Polar transform to sample the original 3D shape data which was obtained using the 3D laser scanner. By mapping the sampled data to a 2D image, we can obtain the shape...
Active Appearance Model (AAM) is a popular technique for facial feature point extraction. However, conventional AAM is always viewpoint-generic, which lowers the fitting accuracy. In this paper, a viewpoint-specific AMM is proposed for robust facial point extraction under multi-viewpoint. We investigate three viewpoints, such as 0 degrees, 30 degrees, 60 degrees. The experimental results show a briefly...
In medical imaging research fields, three-dimensional (3D) shape modeling and analysis of anatomic structures with fewer parameters is one of important issues, which can be used for computer assisted diagnosis, surgery simulation, visualization and many medical applications. The 3-D object shape or surface can be expressed by spherical harmonics. In this paper, we present a spherical harmonics based...
