About Me                                             

I received my Ph.D. degree in Electrical Engineering from University of Connecticut in 2005. My Ph.D. advisor was Prof. Martin D. Fox. Before I came to the U.S., I was trained in mathematics in China and got my B.S. and M.S. degrees in Math. My research interests include image processing, computer vision, medical imaging, and applied mathematics.

Level Set/Active Contour Models for Image Segmentation                                   Back to top

Edge based models:
  1. Level Set Evolution without Re-initialization: A New Variational Formulation, CVPR'05 (oral presentation). Click here to see some demos and download Matlab code for this method. C code for this method is available by email request. This method was improved in my IEEE TIP paper ( try the code). The new paper and the source code will be available here. Note: In the new method, the level set function is intrinsically maintained as an approximate signed distance only near the zero level set.
  2. Fast narrow band implementation of the above method, (pdf, demo code).
  3. Segmentation of external force field for a snake model, CVPR'05.

 
Region based models:

Implementations and further developments:

  1. LBF_v0.1 (.rar or .zip) for Matlab 7.0 or higher versions in Windows.
  2. LBF_v0.5 (with an auxiliary global term) (MICCAI 2008)
  3. LBF_1.0 (simultaneous segmentation and bias field estimation) (MICCAI 2008, oral presentation)
  • Segmentation of brain MR images with intensity inhomogeneity. This model is able to simultaneously segment gray matter, white matter, cerebrospinal fluid (CSF), and the background. One page abstract to appear in ISMRM'08 (oral presentation).
