Trajectory Optimization for Physics-Based Reconstruction of 3d Human Pose from Monocular Video. (arXiv:2205.12292v1 [cs.CV])

We focus on the task of estimating a physically plausible articulated human
motion from monocular video. Existing approaches that do not consider physics
often produce temporally inconsistent output with motion artifacts, while
state-of-the-art physics-based approaches have either been shown to work only
in controlled laboratory conditions or consider simplified body-ground contact
limited to feet. This paper explores how these shortcomings can be addressed by
directly incorporating a fully-featured physics engine into the pose estimation
process. Given an uncontrolled, real-world scene …
