Region-Based 2D Deformable Generalized Cylinder for Narrow Structures Segmentation
In this paper, we present a region-based deformable cylinder model, extending the work on classical region-based active contours and gradient-based ribbon snakes. Defined by a cent...

Deform PF-MT: Particle Filter With Mode Tracker for Tracking Nonaffine Contour Deformations
We propose algorithms for tracking the boundary contour of a deforming object from an image sequence, when the nonaffine (local) deformation over consecutive frames is large and th...
