V2V-PoseNet: Voxel-to-Voxel Prediction Network for Accurate 3D Hand and Human Pose Estimation from a Single Depth Map

PyTorch re-implementation of the V2V-PoseNet is available at dragonbook's repo.

Thanks dragonbook for re-implementation. Other versions of the V2V-PoseNet are also welcome!

Introduction

This is our project repository for the paper, V2V-PoseNet: Voxel-to-Voxel Prediction Network for Accurate 3D Hand and Human Pose Estimation from a Single Depth Map (CVPR 2018).

We, Team SNU CVLAB, (Gyeongsik Moon, Juyong Chang, and Kyoung Mu Lee of Computer Vision Lab, Seoul National University) are winners of HANDS2017 Challenge on frame-based 3D hand pose estimation.

Please refer to our paper for details.

About our code

Dependencies

Our code is tested under Ubuntu 14.04 and 16.04 environment with Titan X GPUs (12GB VRAM).

Code

Clone this repository into any place you want. You may follow the example below.

makeReposit = [/the/directory/as/you/wish]
mkdir -p $makeReposit/; cd $makeReposit/
git clone https://github.com/mks0601/V2V-PoseNet_RELEASE.git
  • src folder contains lua script files for data loader, trainer, tester and other utilities.
  • data folder contains data converter which converts image files to the binary files.

To train our model, please run the following command in the src directory:

th rum_me.lua
  • There are some optional configurations you can adjust in the config.lua.
  • You have to convert the .png images of the ICVL, NYU, and HANDS 2017 dataset to the .bin files by running the code from data folder.
  • The directory where you have to put the dataset files and computed centers of each frame is defined in src/data/dataset_name/data.lua
  • Visualization code is finally uploaded! You have to prepare 'result_pixel.txt' for each dataset. Each row of the result file has to contain the pixel coordinates of x, y and depth of all joints (i.e, x1 y1 z1 x2 y2 z2 ...). Then run pixel2world script and run draw_DB.m

Dataset

We trained and tested our model on the four 3D hand pose estimation and one 3D human pose estimation datasets.

Results

Here we provide the precomputed centers, estimated 3D coordinates and pre-trained models.

The precomputed centers are obtained by training the hand center estimation network from DeepPrior++ . Each line represents 3D world coordinate of each frame. In case of ICVL, NYU, MSRA, and HANDS2017 dataset, if depth map is not exist or not contain hand, that frame is considered as invalid. In case of ITOP dataset, if 'valid' variable of a certain frame is false, that frame is considered as invalid. All test images are considered as valid.

The 3D coordinates estimated on the ICVL, NYU and MSRA datasets are pixel coordinates and the 3D coordinates estimated on the HANDS2017 and ITOP datasets are world coordinates. The estimated results are from ensembled model. You can make the results from a single model by downloading the pre-trained model and testing it.

We used awesome-hand-pose-estimation to evaluate the accuracy of the V2V-PoseNet on the ICVL, NYU and MSRA dataset.
