Lennard-Jones force field for Geometric Active Contour
This paper presents a new Geometric Active Contour (GAC) model based on Lennard-Jones (L-J) force field, which is inspired by the theory of intermolecular interaction. It is diff...

Oblivious routing on geometric networks
We study oblivious routing in which the packet paths are constructed independently of each other. We give a simple oblivious routing algorithm for geometric networks in which the ...

Compressive sensing with local geometric features
We propose a framework for compressive sensing of images with local geometric features. Specifically, let x ∈ RN be an N-pixel image, where each pixel p has value xp. The image...

A geometric interpretation of r-precision and its correlation with average precision
We consider two of the most commonly cited measures of retrieval performance: average precision and R-precision. It is well known that average precision and R-precision are highly...
