Overview

3D-HourGlass-Network

3D CNN Based Hourglass Network for Human Pose Estimation (3D Human Pose) from videos. This was my summer'18 research project.

Discussion

In this work I try to extend the idea in Carriera et. al. CVPR'17 of 3D CNN inflation for action recognition from videos to human pose estimation from videos. We use a pretrained hourglass network with a fully connected depth regressor, inflate the 2D convolutions to 3D convolutions and perform temporal 3D human pose estimation. This inflation helps the network learn features from nearby frames and refine its predictions. Similar idea was used in Girdhar et. al. CVPR'18 (at about the same time!) where they perform multiperson human pose estimartion from videos using an inflated Mask RCNN

Requirements

  • python 3.6
  • pytorch 0.4
  • torchvision
  • progress

Datasets

We used Human 3.6 dataset for this project.

Instructions to run

python main.py -expID [EXP-NAME] -nFramesReg [NUM-FRAMES]

Results

We improved the baseline performance of hourglass network from MPJPE of 64 to MPJPE 62.8 and thus show significance of temporal features in real world problems. This idea could be easily extended for other tasks also like semantic segmentation and object detection.

    Data preparation

    I am trying to run your scripts, but faced with some problems. The main problem is the data issue; you used h36m data set and reprocessed it. My question is about data preparation. Can you please explain how did you do that or can you provide data preparation scripts as well?

    Thank you
