分区变形与多尺度约束结合的3D面皮点对应
3D facial correspondence based on regional deformation and multi-scale constraint
摘要
Abstract
Aiming at the precise 3D point correspondence between faces samples,this paper introduced integral invariants for multi-scale constraints,and proposed a method of 3D point correspondence based on non-rigid regional deformation combined with multi-scale constraints.First,it marked the feature points based on the unified Frankfurt coordinate on pending corresponding faces and reference faces.Second,with completing geodesic partition of faces samples,it deformed each region of faces samples by radial basis function,so that pending corresponding faces'regions approximately coincided with the reference faces'regions.Finally,it selected the corresponding point on reference face according to the stability of the relative positions of faces'regions,and created candidate set of corresponding point on pending corresponding faces,it used the multi-scale constraint based on volume integral invariants to select best corresponding point,thus it achieved 3D point correspondence.The experiments show the proposed algorithm effectively improve the precision of point correspondence.关键词
