3D face reconstruction and recognition based on feature division
HU Yang-ming · Journal of Computer Applications · 2012
The traditional algorithm of 3D face reconstruction is inefficient and it is difficult to meet the requirements of practical application.To address this problem,a feature-slice-based 3D face reconstruction algorithm was proposed.Besides,the feature-slice-based weighed 3D face recognition was proposed on the basis of the reconstruction algorithm.First,a 2D template-based alignment algorithm was developed to process the correspondence between faces automatically,and a linear facial model was built up.Second,an improved Active Shape Model(ASM) algorithm was proposed to locate the feature points and slices in the 3D and 2D face images.Then,every facial feature slices shape was reconstructed by a PCA-based sparse morphable mode.Finally,the algorithm was applied to 3D face recognition.The experimental results show that the presented algorithm has higher efficiency and accuracy,and improves the 3D face recognition rate.
