Datasets for Human Pose Estimation

The number of keypoints varies by dataset. For example, the LSP dataset has 14 keypoints, the MPII dataset has 16 keypoints, and the COCO dataset has 17 keypoints

COCO Dataset

To train on coco (single person pose estimation), place the following files in the right place.

• cocoapi: coco API
• annotations: COCO keypoint dataset
  • person_keypoints_train+val5k2014: annotations (JSON files)
• images: tain and val datasets
  • train2014
  • val2014
• coco_annotations_2014.json or coco_annotations_2014.json: reformatted annotation generated by ./miscs/gen_coco.m

Prepare json annotation file

Please edit year = 2017; % 2014 or 2017 in gen_coco.m to generate the corresponding annotation file (coco2014 or coco2017).

Types of Keypoints and Skeleton Variants

How Different Datasets Define Keypoints and Joint Connections • Common skeleton structures in COCO, MPII, and Human3.6M • Differences in full-body vs. hand vs. face keypoints • Unified keypoint formats for multi-task models
