From skeleton to body: Keypoint Estimation is Helpful for Human Body Reconstruction

Bio photo 2

My works mainly lie in inferring human structures from RGB inputs, which starts from 2D keypoint estimation, towards more complex tasks like 3D skeleton inference and SMPL-based human pose & shape estimation. Along this road, we find that high-level tasks, like human body estimation, can benefit a lot from low-level inferred structures, like 3D skeletons, and vice versa. Furthermore, in our latest work, "Human Pose Regression with Residual Log-likelihood Estimation", we unified all the above HPS tasks in a direct regression paradigm, replacing generally accepted heatmap without loss of accuracy. This work has been accepted by ICCV'21 as Oral.
