Jin Zhang 张晋

I am a Ph.D. student in Mathematics at Beihang University. My public research interests include computer vision, 3D point clouds, machine learning, robust point-set registration, optimal transport, and numerical algorithms for CNC interpolation.

This homepage collects my public academic projects, technical notes, and contact information. I maintain open-source research code on GitHub and write occasional technical notes on my personal blog.

Research overview

Highlights

  • 2026   Released Sinkhorn-CPD, the official implementation of a Computer-Aided Design paper on robust point cloud registration.
  • 2026   Released LMM-Registration, a MATLAB implementation for robust multi-view point-set registration.
  • 2024   Maintained cnc_interpolation, a Python/Jupyter project for CNC interpolation, feedrate planning, look-ahead planning, and toolpath smoothing.

Research

My research interests revolve around geometric computation, 3D vision, and machine learning. Current public projects focus on robust point cloud registration, multi-view point-set alignment, optimal transport, probabilistic modeling, and numerical algorithms for curve interpolation.
