PILOT-C: Physics-Informed Low-Distortion Optimal Trajectory Compression
Summary: PILOT‑C: a physics‑informed, frequency‑domain, error‑bounded trajectory compressor that models motion continuity and time synchronization and compresses axes independently to natively handle n‑D (incl. 3D) trajectories. Empirically outperforms SED‑based CISED‑W (~19% higher compression, ~33% lower error) and 3D SQUISH‑E (~49% better compression) while retaining similar computational complexity.
