Learning to Search on Manifolds for 3D Pose Estimation of Articulated Objects
Yu Zhang, Chi Xu, Li Cheng
This paper focuses on the challenging problem of 3D pose estimation of a diverse spectrum of articulated objects from single depth images. A novel structured prediction approach is…
Lie-X: Depth Image Based Articulated Object Pose Estimation, Tracking, and Action Recognition on Lie Groups
Chi Xu, Lakshmi Narasimhan Govindarajan, Yu Zhang +1
Pose estimation, tracking, and action recognition of articulated objects from depth images are important and challenging problems, which are normally considered separately. In this…
Hand Action Detection from Ego-centric Depth Sequences with Error-correcting Hough Transform
Chi Xu, Lakshmi Narasimhan Govindarajan, Li Cheng
Detecting hand actions from ego-centric depth sequences is a practically challenging problem, owing mostly to the complex and dexterous nature of hand articulations as well as non-…
