Code to evaluate model of paper "Cross-modal Deep Variational Hand Pose Estimation"

Cross-Modal Deep Variational Hand Pose Estimation

Project page

This repository provides a code base to evaluate the trained models of the paper Cross-Modal Deep Variational Hand Pose Estimation and reproduce the numbers of Table 2. It is a modified version of the code found here by Christian Zimmermann, adapted to run our model.

Recommended system

Recommended system (tested):

• Ubuntu 16.04.2 (xenial)
• Python 3.5.2

Python packages used by the example provided and their recommended version:

• tensorflow==1.3.0
• numpy==1.14.5
• scipy==1.1.0
• matplotlib==1.5.3
• pytorch==0.3.1
• opencv-python==3.4.1.15

Preprocessing for training and evaluation

In order to use the training and evaluation scripts you need download and preprocess the datasets.

Rendered Hand Pose Dataset (RHD)

• Download the dataset RHD dataset v. 1.1
• Extract it.
• In the file 'create_binary_db.py', set the variable 'path_to_db' to the path of the extracted dataset.
• Run

python create_binary_db.py

• This will create a binary file in ./data/bin according to how 'set' was configured. Keep it at 'evaluation'.

Stereo Tracking Benchmark Dataset (STB)

• To run the dataset on STB, it is neecessary to get the dataset presented in Zhang et al., ‘3d Hand Pose Tracking and Estimation Using Stereo Matching’, 2016
• The link to the dataset can be found here
• Unzip the dataset
• In 'create_db.m', set 'PATH_TO_DATASET' to the path of the extracted dataset
• Run

cd ./data/stb/
matlab -nodesktop -nosplash -r "create_db"

• This will create the binary file ./data/stb/stb_evaluation.bin

Trained models

• The trained models can be found here.
• After downloading the models, unzip it into the main project directory.

Evaluation

• To reproduce the numbers of table 2, set the desired experimental settings in 'evaluate_model.py'. These correspond to the following parameters in the paper:

Paper	Code
H	hand_side_invariance
S	scale_invariance

• Run

python evaluate_model.py

• This will create a folder named 'eval_results' in the respective model folder in which the PCK curve and some predictions are saved.
