Research of the Ear Reconstruction Based on the Poisson Image Blending.

Due to the undesirable reconstruction result of the ear part in the 3D face reconstruction which based on single image, we propose an ear reconstruction approach based on the Poisson image blending method. First of all, the 3D face shape is reconstructed from the single frontal image by fitting the sparse morphable model. Then the cylindrical expansion approach and the elliptical skin color criterion are combined in order to utilize for the texture reconstruction and correction process. Finally, the Poisson image blending method is selected to carry out the second recovery for the ear part. The experiment results demonstrate that our approach not only ensure a fast and simplified reconstruction process but also efficiently improve the undesirable reconstruction result in the face profile especially the ear part, which has existed in some 3D face modeling technologies. Meanwhile, it further enhances the sense of reality of the reconstruction result.
