This is a pytorch implementation of V2V-PoseNet(V2V-PoseNet: Voxel-to-Voxel Prediction Network for Accurate 3D Hand and Human Pose Estimation from a Single Depth Map), which is largely based on the author's torch7 implementation and pytorch implementation.

This repository adds

• An experiment demo on ITOP human pose dataset, result in ~6.5cm mean error

• pytorch 0.4.1 or pytorch 1.0
• python 3.6
• numpy
• h5py

• Clone this repo:

git clone https://github.com/YangYangTaoTao/V2V-Pose.git
cd V2V-PoseNet_Pytorch

• Download ITOP dataset and extract to directory ./datasets/depthmap(h5 files, including depth image and labels).

for training and testing：
python main.py

visual result：
python show_acc.py

demo on ITOP test image：
python demo.py --is_h5 fid = id_number(eg:55)

demo on custom image：
python demo.py --fx=190.41 --fy=190.41

-3D result visualization, refer to official implementation for more details. Here are some results:

Replaced V2V-PoseNet's loss with PoseFix's loss(one-hot heatmap loss + L1 coord loss), and it's independently implemented under ./integral-pose directory. Also, configure data_dir and center_dir in ./integral-pose/main.py, and start training. The result shows about 10mm mean error.

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.

In this repository, we provide

• Our model architecture description (V2V-PoseNet)
• HANDS2017 frame-based 3D hand pose estimation Challenge Results
• Comparison with the previous state-of-the-art methods
• Training code
• Datasets we used (ICVL, NYU, MSRA, ITOP)
• Trained models and estimated results
• 3D hand and human pose estimation examples

• Torch7
• CUDA
• cuDNN

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

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 and NYU 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

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

• ICVL Hand Poseture Dataset [link] [paper]
• NYU Hand Pose Dataset [link] [paper]
• MSRA Hand Pose Dataset [link] [paper]
• HANDS2017 Challenge Dataset [link] [paper] [challenge benchmark paper]
• ITOP Human Pose Dataset [link] [paper]

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 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 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.

• NYU Hand Pose Dataset [center_trainset] [center_testset] [estimation] [models]
• MSRA Hand Pose Dataset [center] [estimation] [models]
• ITOP Human Pose Dataset (front-view) [center_trainset] [center_testset] [estimation] [models]
• ITOP Human Pose Dataset (top-view) [center_trainset] [center_testset] [estimation] [models]

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

Belows are qualitative results.
