edge/app.py run_once used ONE shared KeypointSmoother across all persons BEFORE tracking assigned IDs. The smoother holds per-joint-index One-Euro filter state, so with >1 person in frame the filter state was shared and corrupted across different people, and same-timestamp calls within a frame would pass through unsmoothed while still clobbering the shared state. Multi-person scenes could get corrupted torso angles -> missed/false falls. Add TrackSmootherPool (edge/smoothing.py) that lazily allocates one KeypointSmoother per track_id. run_once now: tracks raw keypoints first, then smooths each track's latest frame in place using its own pooled smoother, and forgets a track's smoother when the track is lost (ties into FIX 5 lost-track cleanup). BEHAVIOR CHANGE: keypoints are now smoothed after tracking instead of before. Single-person pipelines are unaffected (still one smoother, one identity). Multi-person pipelines get correct, non-cross-contaminated smoothing. run_once signature: smoother param replaced with pool: TrackSmootherPool. build_pipeline now constructs "pool" instead of "smoother". Tests: tests/test_smoothing.py adds TrackSmootherPool identity/forget coverage; tests/test_app.py adds test_two_persons_get_independent_smoothing demonstrating each track's smoothed keypoints stay on its own side instead of being pulled toward the other person. |
