Measuring Elongation from Shape Boundary
Abstract Shape elongation is one of the basic shape descriptors that has a very clear intuitive meaning. That is the reason for its applicability in many shape classification tasks...

Fusion Graphs: Merging Properties and Watersheds
Region merging methods consist of improving an initial segmentation by merging some pairs of neighboring regions. In this paper, we consider a segmentation as a set of connected r...

PHLST5: A Practical and Improved Version of Polyharmonic Local Sine Transform
We introduce a practical and improved version of the Polyharmonic Local Sine transform (PHLST) called PHLST5. After partitioning an input image into a set of rectangular blocks, t...

Sampling and Reconstruction of Surfaces and Higher Dimensional Manifolds
We present new sampling theorems for surfaces and higher dimensional manifolds. The core of the proofs resides in triangulation results for manifolds with boundary, not necessarily...

A Geometric Approach for Regularization of the Data Term in Stereo-Vision
Every stereovision application must cope with the correspondence problem. The space of the matching variables, often consisting of spatial coordinates, intensity and disparity, is...

Estimation of Vector Fields in Unconstrained and Inequality Constrained Variational Problems for Segmentation and Registration
Vector fields arise in many problems of computer vision, particularly in non-rigid registration. In this paper, we develop coupled partial differential equations (PDEs) to estimat...
