Framework

Pose-triplet contains three components: estimator, imitator and hallucinator

The three components form dual-loop during the training process, complementing and strengthening one another. alt text

Improvement through co-evolving

Here is imitated motion of different rounds, the estimator and imitator get improved over the rounds of training, and thus the imitated motion becomes more accurate and realistic from round 1 to 3. alt text

Video demo

Comparasion

Here we compared our results with two recent works Yu et al. and Hu et al.

Installation

  • Please refer to README_env.md for the python environment setup.

Data Preparation

Training

Please refer to script-summary for the training process. We also provide a checkpoint folder here with better performance, which support that this framework has the potential to reach the same performance as fully-supervised approaches.
Note: checkpoint for the RL policy is not include due to the size limitation, please following the training code to train the policy.

Inference

We provide an inference code here. Please follow the instruction and download the pretrained model for inference on videos.

Talk

Here is a slidestalk (PPT in english, speak in chinese).
