Face Reconstruction Algorithm Based on Small Curve Relaxation Constraint Approximation
一种曲线松弛约束逼近的三维人脸图像建模算法

Aiming at the problem that face feature expression change is very complex, and the traditional modeling methods can't good depict subtle expression changes, and the realistic face modeling is not strong, this paper proposed 3d face modeling algorithm based on a small area the approaching a point curve. The three dimensional area face expres- sion changes arc relatively rich. This paper made small region partition of the area used points approximation technology to simulate more complex curve profile, to avoid the abuses of dipict and characteristics simulation distortion when using traditional algorithm based on the features of the straight line. This method can restore good 3d face expressions change relatively rich area feature information, making 3d face modeling more realistic, and features depict higher accuracy.
