> > | What is the contribution of the paper?
This paper focused on the physically-based dynamics for human motion tracking. This approach can produce naturally tracking reaction for the changing of environment and motion properties, such as mass distribution, speed. In this paper, the author design a generative model for human tracking with a stochastic controller to generate muscle forces, and a higher-dimensional kinematic model conditioned on the low-dimensional dynamics.
How are the results evaluated?
This paper evaluates the result by doing four experiments. The first three experiments use the same set of parameters for the kinematic evolution and the same prior over the control parameters for the dynamics. The parameters for the fourth experiment were set to similar values, but adjusted to account for a difference in frame rate. The first experiment tested the when changing the speed. The second one focused on dealing with occlusion. The third test was for turning in the 3D world. And the last experiment report results on the HumanEva benchmark dataset.
Is the paper reproducible?
Except for no source code, this paper is reproducible. The dataset used here is available and the tracking parameter is shown in the paper.
How could the paper research or paper writing be improved?
If the examples in the paper are on different human models, it will be better. I mean like on male/female, the young/elder, short/high, thin/fat.
