Face Alignment Algorithm Based on of Bayesian Tangent Shape Model
Wang Ai-yun · Jisuanji gongcheng · 2009
This paper proposes a novel face alignment algorithm:improved Bayesian Tangent Shape Model(BTSM).It isolates gesture parameters and shape parameters,deals with these two parameters respectively and uses radius of curvature as the number of dynamic search of this landmark.Experiments show that the algorithm can make up for the defects that BTSM can not well handle the alignment of multi-gesture face images and the approach can improve the effectiveness in both speed and accuracy.
