Journal ArticleDOI
Physical states in G/G models and two-dimensional gravity
TL;DR: In this article, the BRST cohomology of the G/G topological models is analyzed for the case of A 1 (1), where the singular vector structure and fusion rules are employed to translate the latter into the cohomological on the space of irreducible representations.
Proceedings ArticleDOI
Prior-based segmentation by projective registration and level sets
TL;DR: A novel variational approach to prior-based segmentation is suggested, which accounts for planar projective transformation, using a single reference object, and is derived from two-view geometry.
Journal ArticleDOI
Shape-Based Mutual Segmentation
TL;DR: A novel variational approach for simultaneous segmentation of two images of the same object taken from different viewpoints, with a unified level-set framework for region and edge based segmentation associated with a shape similarity term.

Affine-invariant geodesic geometry of deformable 3D shapes
TL;DR: In this paper, the affine invariant arclength for surfaces in R^3 is defined and the surface metric tensor can be treated as a canonical Euclidean object on which most traditional shape analysis tools can be applied.
Book ChapterDOI
Efficient Beltrami flow using a short time kernel
Alon Spira,Ron Kimmel,Nir Sochen +2 more
TL;DR: A short time kernel for the Beltrami image enhancing flow is introduced and can be used for arbitrary large time steps in order to produce adaptive smoothing and/or a new scale-space.
