WebA Unified Multi-output Semi-supervised Network for 3D Face Reconstruction. Abstract: In this paper, we propose a method to reconstruct fine-grained 3D faces from single images base on a nearly unified multi-output regression network. The network estimates the facial shape, normal and appearance jointly in 2D UV map which preserves spatial ... WebSpherical Unwarp. The Spherical Unwarp module performs an unwarping operation on an image in order to remove warping on the border edges of an image. This warping is caused by lens distortion that causes objects …
