git clone https://github.com/Ha0Tang/HandGestureRecognition
cd HandGestureRecognition/

This code requires MATLAB. Please install it.

Dataset Preparation

For Cambridge Hand Gesture or Northwestern Hand Gesture, the datasets must be downloaded beforehand. Please download them on the respective webpages. Please cite their papers if you use the data.

Preparing Cambridge Hand Gesture Dataset. The dataset can be downloaded here. You can also download this dataset use the following script:

bash ./datasets/download_handgesture_dataset.sh Cambridge_Hand_Gesture

Preparing Northwestern Hand Gesture Dataset. The dataset is proposed in this paper. You can download this dataset use the following script:

bash ./datasets/download_handgesture_dataset.sh Northwestern_Hand_Gesture

Preparing HandGesture Dataset. This dataset consists of 132 video sequences of 640 by 360 resolution, each of which recorded from a different subject (7 males and 4 females) with 12 different gestures (“0”-“9”, “NO” and “OK”). Download this dataset use the following script:

bash ./datasets/download_handgesture_dataset.sh HandGesture

Preparing Action3D Dataset. This dataset consists of 1620 image sequences of 6 hand gesture classes (box, high wave, horizontal wave, curl, circle and hand up), which are defined by 2 different hands (right and left hand) and 5 situations (sit, stand, with a pillow, with a laptop and with a person). Each class contains 270 image sequences (5 different situations × 2 different hands × 3 times × 9 subjects). Each sequence was recorded in front of a fixed camera having roughly isolated gestures in space and time. All video sequences were uniformly resized into 320 × 240 in our method. Download this dataset use the following script:

bash ./datasets/download_handgesture_dataset.sh Action3D

Training New Models

New models can be trained with the following commands.

1. Prepare your own dataset like in this folder.

2. Extract key frame:

matlab -nodesktop -nosplash -r "key_frames_extraction"

Key frames will be extrated in the folder ./datasets/sample_keyframe.

3. Go this folder for further processes.
