基于变形与测地距离一致性约束的3D面皮点对应
3D facial correspondence based on deformation and geodesic distance consistency constraint
摘要
Abstract
Aiming at the 3D physiology point correspondence between faces samples,considering the advantages of geodesic distance in describing complex surface shape, this paper proposed a new 3D facial physiology correspondence method based on model deformation and geodesic distance consistency constraint. Firstly, it marked feature points based on the Frankfurt coordinate and the face model deformed based on thin plate spline function according to the correspondence of feature points. Secondly , it established the initial correspondence set according to the geometric feature vector of feature points, then pruned the initial correspondence set depending on geodesic distance consistency constraint in order to generate a kernel set. Finally, it extended the kernel set until each vetex on source model has corresponded. Experimental results prove that this method improves the precision of point correspondence, and it can establish 3D face physiology point correspondence effectively.关键词
