Skeletal Pose Accuracy
AI is playing a leading role in raising performance across a range of professional sports. Detailed analytics and movement analysis are helping coaches and players improve tactically and technically.
AI is also at the core of a new generation of remote fitness applications. Apps and fitness mirrors, enhanced with embedded AI, can track and analyze body movements, helping athletes optimize home workouts.
Engai creates accurate image and video training datasets in partnership with industry leaders. Our experienced managers and skilled in-house annotation team are happy to meet the needs of today's cutting-edge sport and fitness machine learning projects.
Sport / Capabilities
Sport Core Solutions
Carefully annotated data for sport perception, automation and research.
Sport label taxonomy
Define classes for athletes, body landmarks and playing areas, with visual examples and explicit boundary rules.
Capture-aware quality review
Review the effects of lighting, scale and occlusion in training sessions, match footage and exercise recordings.
Model-ready annotation data
Connect sport labels to source identifiers, scene metadata and the export schema your model uses.

Careful work on the small details
The sample batch helped us agree on how to handle overlapping leaves and partially visible crops.

Having those edge cases discussed early would give our team a clearer baseline before scaling annotation.
Clear communication throughout
Our labeling requirements evolved as we reviewed the imagery. The feedback process felt straightforward.
Read more
A shared set of examples and regular checkpoints would help keep the dataset consistent across batches.
A practical approach to field data
Field images are rarely perfect. We appreciated the attention to shadows, occlusion and changes in lighting.
