# 2D Hand Keypoint Datasets

It is recommended to symlink the dataset root to `$MMPOSE/data`.
If your folder structure is different, you may need to change the corresponding paths in config files.

For [NVGesture](https://www.v7labs.com/open-datasets/nvgesture) data and annotation, please download from [NVGesture Dataset](https://drive.google.com/drive/folders/0ByhYoRYACz9cMUk0QkRRMHM3enc?resourcekey=0-cJe9M3PZy2qCbfGmgpFrHQ&usp=sharing).
Extract them under {MMPose}/data, and make them look like this:

The hand bounding box is computed by the hand detection model described in [det model zoo](/demo/docs/mmdet_modelzoo.md). The detected bounding box can be downloaded from [GoogleDrive](https://drive.google.com/drive/folders/1AGOeX0iHhaigBVRicjetieNRC7Zctuz4?usp=sharing). It is recommended to place it at `data/nvgesture/annotations/bboxes.json`.
