Racket perception pipeline
A staged perception pipeline detects court, players, ball, contacts, bounces, and rally structure.
Built for accountable production
See the point. Find the decision. Review the frame.
UNFORCE turns racket-match video into tactical sequences, rally patterns, shot context, and coaching debriefs that stay linked to the original frame evidence.
Repository-backed product facts · reviewed 26 August 2026
Architecture and value
Move from a match-wide pattern to the exact rally and frame, add human tactical context, and leave with a small number of reviewable priorities.
Frame-addressable event graph
A frame-addressable event graph links tactical statements back to source moments and confidence.
Human-reviewed debrief
The debrief layer groups repeatable patterns and preserves coach annotation rather than replacing it.

Technical invariants
Frame provenance
Every derived event retains a source frame or an explicit unavailable state.

Visible uncertainty
Ambiguity is surfaced; the system does not manufacture contact, intent, or line truth.

Current status. Post-match analysis is the boundary; it does not claim live officiating, medical diagnosis, or certainty where the video is unreadable.
Frequently asked questions
What is the safest way to evaluate it?
Start with the architecture, reproduce the documented workflow, and verify the boundary against your own threat model.
Does the comparison include live third-party pricing?
No. Mutable vendor pricing is deliberately excluded. Verify current vendor terms before a purchase decision.
Where are limitations documented?
The status note, architecture page, and engineering articles state the current boundary and failure behaviour.
