Use supported tracked geometry to localize participants and equipment through time. Refine keyframes at motion changes and visibility boundaries.
Apply an explicit skeleton definition and place landmarks on the corresponding anatomy. Review point visibility and consistency across frames.

It is the labeling of people, poses, equipment, and observable actions across recorded video. The resulting training data supports activity recognition, pose estimation, and sports tracking models.
Yes. Define the relevant skeleton or point structure for the task and apply it consistently. Guidelines should explain point placement, visibility, and how to handle occluded anatomy.
Yes. Use defined dynamic properties on relevant tracks or frames and review their timing against the original recording. Clear action definitions help reduce boundary disagreements.
Yes. Annotators can label the visible object and refine its keyframes. Difficult motion, blur, and occlusion still require review against the source frames.
A useful label has an observable definition, consistent timing rules, and representative examples. Expert review should resolve ambiguous actions and pose placements before release.
Define shared classes, structured properties, and clear labeling instructions before work starts. Use representative examples and contextual review to resolve disagreements in the sports and human activity recognition dataset.
Yes. Route video annotation through Review and Rework stages. Reviewers can inspect the source data, correct labels, and send an item back when more work is needed.
Yes. Use dataset search, metadata, tags, and available filters to select relevant video assets. Keep representative conditions and difficult examples visible in the preparation workflow.
Export reviewed video annotations in a supported format appropriate to the label types. Dataset versions help teams identify which prepared examples belong to the training or evaluation release.
