Ming-Ching Chang

I am a PhD candidate in Laboratory for Engineering Man/Machine Systems (LEMS), Division of Engineering, Brown University, working on computer vision, shapes/geometry, and medical imaging. Specifically, my work focuses on 2D/3D medial shape representation (shocks) and applications, e.g., shape (mesh) recontruction, geodesic computations, shape matching, etc. (advisor: Prof. Benjamin B. Kimia).

Research

3D medial representation (Medial Axis/Medial Scaffold): including geometry and computations related to 3D Voronoi Diagram/Delaunay Triangulation.
Application of Medial Scaffold to surface meshing, shape reconstruction, and skeleton-based animation.
3D shape registration/recognition: study the Medial Scaffold transitions and match them robustly using the Medial Scaffold representation.
Archaeological pot fragment re-assembly in the S.H.A.P.E. Lab.
Computation of 2D/3D medial axis (shocks, singularities of distance transforms, including their geometry/dynamics) by propagating the wavefronts/shocks.
Exact geodesic computation by studying the geodesic wavefronts/shocks on surface meshes.

I use the VXL C++ library for computer vision research.
