This repository contains the demo code for Pose-REN, an accurate and fast method for depth-based 3D hand pose estimation.

• caffe-pose
• OpenCV (with python interface)
• Optional: librealsense (for live demo only)

Clone caffe-pose:

git clone https://github.com/xinghaochen/caffe-pose.git

Install caffe:

cd caffe-pose
cp Makefile.config.example Makefile.config
# uncomment WITH_PYTHON_LAYER := 1
# change other settings accordingly
make -j16
make pycaffe -j16

Add path/to/caffe-pose/python to PYTHONPATH.

We use a new layer called GenerateROILayer in Pose-REN and the python and c++ implementations are located in src/libs.

If you prefer using python layer, add path/to/src/libs to PYTHONPATH, otherwise copy generate_roi_layer.hpp/cpp to caffe-pose, update caffe.proto with the provided patch caffe.patch.proto and build caffe again.

The tables below show the predicted labels and pretrained models on ICVL, NYU and MSRA dataset. All labels are in the format of (u, v, d) where u and v are pixel coordinates.

Please use the Python script src/show_result.py to visualize the predicted results:

$ python src/show_result.py icvl your/path/to/ICVL/test/Depth --in_file=results/NEUCOM18_ICVL_Pose_REN.txt

You can see all the testing results on the images. Press 'q' to exit.

First copy and modify the example config.py for your setup. Please change data_dir and anno_dir accordingly.

$ cp config.py.example config.py

Use the Python script src/testing/predict.py for prediction with predefined centers in labels directory:

$ python src/testing/predict.py icvl your/path/to/output/file.txt

The script depends on pycaffe.

Please see here for how to evaluate performance of hand pose estimation.

We provide a realtime hand pose estimation demo using Intel Realsense device. Note that we just use a naive depth thresholding method to detect the hand. Therefore, the hand should be in the range of [0, 650mm] to run this demo. We tested this realtime demo with an Intel Realsense SR300.

Please use your right hand for this demo and try to avoid clustered foreground and redundant arm around the hand.

First compile and install the librealsense and its python wrapper. After everything is working properly, just run the following python script for demo:

python src/demo/realsense_realtime_demo_librealsense2.py

By default this script uses pre-trained weights on ICVL dataset. You can change the pre-trained model by specifying the dataset.

python src/demo/realsense_realtime_demo_librealsense2.py  nyu/msra/icvl/hands17

Notes: The speed of this python demo is not optimal and it runs slightly slower than the c++ demo.

First compile and build:

cd src/demo/pose-ren-demo-cpp
mkdir build
cd build
cmake ..
make -j16

Run the demo by:

cd ..                 # redirect to src/demo/pose-ren-demo-cpp
./build/src/PoseREN   # run

By default it uses pre-trained weights on Hands17 dataset. You can change the pre-trained model by specifying the dataset.

./build/src/PoseREN  nyu/msra/icvl/hands17

Notes: This C++ demo is not fully developed and you may have to deal with some dependency problems to make it works. It serves as a preliminary project to demonstrate how to use Pose-REN in C++.

Our code and pre-trained models are available for non-commercial research purposes only.
