Research:

I am currently doing research in the fields of medical image processing and analysis, such as image segmentation and physics-based simulation using deformable models.

Check my Resume (pdf).

• Intermodality registration and strain comparison with ultrasound. [pdf]

• Learning based automatic segmentation and tracking of myocardial boundaries. [pdf]

• A new tag removal method that preserves the orignial image's appearance. [pdf]

• An integrated 4D Segmentation and Tracking system for cardiac tagged MRIs via spatio-temporal propagation. This system is developed in a Matlab 6.5 GUI environment. It achieves high processing speed with the minimal human interactions. [pdf]

  

• A FEM model of the deformation of the spinal cord of a rat under external perturbation.
  • 3D Finite Element Models from the segmentation of the white and gray matters.

  

• 3D vertebra segmentation and reconstruction.



• 2D motion under external force.

• Myocardium Tracking based on Gabor filtering. This tracking result gives a good estimation of the boundary propagation for the boundary segmentation purpose.

• Segmentation of cardiac MRI tagging lines using Gabor filter bank. This method has a better performance than HARP.

  

• Tag-removal method and epicardium and endocardium segmentation result using Gabor filter bank and GVF snake.
