Ming-Ching Chang

I got my Ph.D. from the Laboratory for Engineering Man/Machine Systems (LEMS), Division of Engineering, Brown University at Sep., 2008.
I am a computer scientist at the Visualization and Computer Vision (VCV) group at the GE Global Research Center since Nov. 2008.
My research at LEMS supervised by Prof. Benjamin B. Kimia is primarily on computer vision, shapes/geometry, and medical imaging. Specifically, my works focus on 2D/3D medial representation (the ''shocks'' and the "Medial Scaffold") and their applications, e.g., shape (mesh) recontruction, geodesic computations, 3D medial axis regularization, symmetry-based shape matching, etc.

Ph.D. 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 (also LEMS VXL, GE VXL, ITK) C++ libraries for doing computer vision research.
