Key Point Annotation

Precisely detect shape variations for motion tracking, facial landmark detection, and hand gesture recognition.

Highly Flexible Tools

Connect key points to build a skeleton and establish relationships to understand more easily what is labeled. Set up any custom shape including skeletons, hands, and eyes.

Efficient Annotation Platform

Our expert annotators can efficiently extrapolate shapes across frames by moving the grouped points along.

Full Spectrum Labeling

Custom classes, multiple attributes per instance, and hierarchical relationships are available to meet your needs.
