_displacement (mean per-keypoint delta between the last two track frames, normalized by bbox height) was duplicated verbatim in edge/detectors/fall.py and edge/detectors/immobility.py. Move it to edge/geometry.py as track_displacement(track) and have both detectors call the shared helper instead of their own private copy. Pure refactor — behavior is identical (byte-identical formula), no config or public API changes. Tests: tests/test_geometry.py adds direct coverage for the new public helper (fewer-than-two-frames default, and the normalized-by-height calculation). Existing fall/immobility tests are unchanged and stay green, confirming behavior parity. |
