Virtual Fly-Over: A New Visualization Technique For Virtual Colonoscopy
In this paper, we propose a new visualization technique for virtual colonoscopy (VC). The proposed method is called Virtual Fly-Over, which splits the entire colon anatomy into e...

Convex Optimization for Deformable Surface 3-D Tracking
3?D shape recovery of non-rigid surfaces from 3?D to 2?D correspondences is an under-constrained problem that requires prior knowledge of the possible deformations. State-of-the-a...

Interpretation of uniform translational image motion: DCT versus FT
We study properties of the discrete cosine transform (DCT) when applied to an image sequence formed by uniformly translating a still image. The Fourier transform (FT) applied to s...

Stream Line and Path Line Oriented Topology for 2D Time-Dependent Vector Fields
Topological methods aim at the segmentation of a vector field into areas of different flow behavior. For 2D time-dependent vector fields, two such segmentations are possible: eith...

Mining Protein Contact Maps
The 3D conformation of a protein may be compactly represented in a symmetrical, square, boolean matrix of pairwise, inter-residue contacts, or "contact map". The contact...
