DimWeaver: Dimensional Weaved Trajectory Compression

Summary: DimWeaver compresses 2D/3D trajectories by decoupling dimensions, weaving error budgets across components, and grouping similar-velocity 1D segments. It achieves superior compression and lower reconstruction RMSE than existing simplification methods. (summarized by gpt-5.6-luna on Jul 26 2026)
