A Stereo Matching based 3D Face Reconstruction Algorithm

An improved algorithm based on stereo matching technology is proposed to generate 3D face model. By improving and combining the region growing and dynamic programming methods together, a new algorithm of stereo matching is proposed. By processing region growing and dynamic programming methods on two nearly perpendicular directions separately, this new algorithm implements smooth restriction on multi-directions along with effective control of processing direction, which has improved the accuracy of matching notably. Besides, by choosing the outlines of face features as the baselines of region growing, the information of face characters also assists matching. This further improves the accuracy. Experimental results show that the reconstruction results are smooth and vivid.
