The notion of meaningful scale was recently introduced to detect the amount of noise present along a digital contour (Kerautret and …

The analysis of digital shapes requires tools to determine accurately their geometric characteristics. Their boundary is by essence …

We address the problem of computing the exact characteristics of any subsegment of a digital straight line with known characteristics. …

We propose in this paper a new curvature estimator based on the set of maximal digital circular arcs. For strictly convex shapes with …

Deformable models have shown great potential for image segmentation. They include discrete models whose combinatorial formulation leads …

This paper presents a formal framework for representing all reversible polygonalizations of a digital contour (i.e. the boundary of a …

We propose a novel approach to reconstruct shapes from digital data. Contrarily to most methods, reconstructed shapes are smooth with a …

The Minimum Length Polygon (MLP) is an interesting first order approximation of a digital contour. For instance, the convexity of the …

In image processing and pattern recognition, the accuracy of most algorithms is dependent on a good parameterization, generally a …
