Characterizing and Detecting Toric Loops in n-Dimensional Discrete Toric Spaces
Toric spaces being non-simply connected, it is possible to find in such spaces some loops which are not homotopic to a point: we call them toric loops. Some applications, such as t...

Decomposition and Construction of Neighbourhood Operations Using Linear Algebra
In this paper, we introduce a method to express a local linear operated in the neighbourhood of each point in the discrete space as a matrix transform. To derive matrix expressions...

An Improved Coordinate System for Point Correspondences of 2D Articulated Shapes
To find corresponding points in different poses of the same articulated shape, a non rigid coordinate system is used. Each pixel of each shape is identified by a pair of distinct c...

Reconstruction of Discrete Sets with Absorption
A generalization of a classical discrete tomography problem is considered: Reconstruct binary matrices from their absorbed row and columns sums, i.e., when some known absorption is...

Discrete Bisector Function and Euclidean Skeleton
Abstract. In this paper, we propose a new definition and an exact algorithm for the discrete bisector function, which is an important tool for analyzing and filtering Euclidean s...
