## Detailed Description

### ChaLearn Looking at People

Implements loading dataset:

"ChaLearn Looking at People": http://gesture.chalearn.org/

Usage

1. Follow instruction from site above, download files for dataset "Track 3: Gesture Recognition": `Train1.zip`-`Train5.zip`, `Validation1.zip`-`Validation3.zip` (Register on site: www.codalab.org and accept the terms and conditions of competition: https://www.codalab.org/competitions/991#learn_the_details There are three mirrors for downloading dataset files. When I downloaded data only mirror: "Universitat Oberta de Catalunya" works).
2. Unpack train archives `Train1.zip`-`Train5.zip` to folder `Train/`, validation archives `Validation1.zip`-`Validation3.zip` to folder `Validation/`
3. Unpack all archives in `Train/` & `Validation/` in the folders with the same names, for example: `Sample0001.zip` to `Sample0001/`
4. To load data run:
   ./opencv/build/bin/example_datasets_gr_chalearn -p=/home/user/path_to_unpacked_folders/

### Sheffield Kinect Gesture Dataset

Implements loading dataset:

"Sheffield Kinect Gesture Dataset": http://lshao.staff.shef.ac.uk/data/SheffieldKinectGesture.htm

Usage:

1. From link above download dataset files: `subject1_dep.7z`-`subject6_dep.7z`, `subject1_rgb.7z`-`subject6_rgb.7z`.
2. Unpack them.
3. To load data run:
   ./opencv/build/bin/example_datasets_gr_skig -p=/home/user/path_to_unpacked_folders/
