### Dataset Summary

![](https://github.com/hukenovs/hagrid/blob/master/images/hagrid.jpg?raw=true)

We introduce a large image dataset **HaGRID** (**HA**nd **G**esture **R**ecognition **I**mage **D**ataset) for hand gesture recognition (HGR) systems. You can use it for image classification or image detection tasks. Proposed dataset allows to build HGR systems, which can be used in video conferencing services (Zoom, Skype, Discord, Jazz etc.), home automation systems, the automotive sector, etc.

**HaGRID** size is **716GB** and dataset contains **552,992 FullHD** (1920 × 1080) RGB images divided into **18** classes of gestures. Also, some images have `no_gesture` class if there is a second free hand in the frame. This extra class contains **123,589** samples. The data were split into training **92%**, and testing **8%** sets by subject **user-id**, with **509,323** images for train and 43,669 images for test.

![](https://github.com/hukenovs/hagrid/raw/master/images/gestures.jpg)

The dataset contains **34,730** unique persons and at least this number of unique scenes. The subjects are people from 18 to 65 years old. The dataset was collected mainly indoors with considerable variation in lighting, including artificial and natural light. Besides, the dataset includes images taken in extreme conditions such as facing and backing to a window. Also, the subjects had to show gestures at a distance of 0.5 to 4 meters from the camera.

## Annotations
The annotations consist of bounding boxes of hands with gesture labels in COCO format `[top left X position, top left Y position, width, height]`. Also annotations have markups of `leading hands` (`left` of `right` for gesture hand) and `leading_conf` as confidence for `leading_hand` annotation. We provide `user_id` field that will allow you to split the train / val dataset yourself.

## Downloads
We split the train dataset into 18 archives by gestures because of the large size of data. Download and unzip them from the following links:
