Research progress and development tendencies of deep-learning-based single-image 3 dimensions(3D)human reconstruction methods in the past five years were summarized.First,a series of the current state-of-the-art single-image 3D human reconstruction methods were combed from both the perspectives of model representation and computing method.For model representation,the four common representations,including depth image and point cloud representation,parametric body model representation,voxel and semantic voxel representation,and implicit surface function representation,as well as their mutual tra...
