- track_informativeness.py: compare abs-motion vs affine/low-rank residual vs
motion/subspace clustering vs DINOv2 semantic embeddings for scoring which
point tracks are informative; per-clip camera-motion metric; gradio viz.
- sampling_viz.py: render the exact _augment_tracks sampler (coverage + low-rank
weighted + uniform) on a preprocessed dataset to inspect which traces it keeps.
- find_static_windows.py: phase-correlation per-frame camera-motion signal (recovers
after turns) + greedy non-overlapping static-window extraction to build a
relatively-still clip dataset from long untrimmed videos.
- segment_viz.py: FastSAM config sweep + fixes (config/clip filters, allowed_paths).
