Overview

This dataset holds 26,677 images labelled with keypoints on the hand skeleton (21 keypoints), one instance per object. The most common auto-detected tags are hand, person, working, face, top-down view, sitting. It is ready to import into a workspace, export in a dozen formats, or train a model on.

Skeleton

Each object is one instance: its keypoints share an instance_id and are named for their joint. A keypoint that is labelled but hidden carries occluded: true. The joints are in this order in every export (a COCO keypoint array follows it).
