This archive contains the Julia analysis code and trajectory data associated with the manuscript “Outlier-Robust Axial Trajectory Smoothing in Holographic Particle Tracking.” It includes numerical benchmark datasets, detected and ground-truth trajectory CSV files, derived trajectory outputs from the evaluated smoothing methods, summary tables used for quantitative evaluation, and plotting scripts/source data for reproducing the figures. The archive is intended to support reproducibility of the proposed axial trajectory smoothing method and the numerical analyses reported in the paper.
