Registration Project: Conduct research in defining new
coordinate systems by exploring anatomical landmarks such as
teniae coli and haustral folds in CT colonography. Use teniae
coli-constrained virtual colon dissection and flattening to
register supine and prone scans for polyp registration and
Computer-Aided Detection Projection: Investigate textural
features such as colon wall thickness and density histogram
matching, and structural features such as curvatures for
automatic colonic polyp detection and classification.
Investigate various curvature estimation methods such as kernel
convolution, surface patch fitting, Knusson mapping, normalized
volume fitting. Use Pareto fronts and multiobjective genetic
algorithms to compare and design various curvature-based region
Segmentation Project: Investigated new differentiation
estimation methods for noisy data. Analyzed shape features of
2D and 3D images by using their second derivatives and Hessian
matrix analysis. Enhanced and segmented line and sheet features
by their distinctive shape characteristics. Applied the
algorithms to angiography, MRI, and confocal data to extract
blood vessels, white matter, and cytoskeleton fibers.
Surface Fitting Project: Constructed approximation surfaces to
point cloud data such as range images taken from 3D laser
scanners. The surface was defined implicitly as the isosurface
of a trivariate volume model which was obtained as a least
squares fit to the point cloud data.
Normals Estimation Project: Approximated normals for locally
supported isosurfaces for the Marching Cubes algorithm.
Identified the cause of poor estimates for the conventional
method. Developed topology-based methods for computing the
normal estimates of a triangular mesh isosurface accurately and
