Deformable Model with a Complexity Independent from Image Resolution
Jacques-Olivier Lachaud, Benjamin Taton
We present a parametric deformable model which recovers image components with a complexity independent from the resolution of input images. The proposed model also automatically ch…
Combinatorial pyramids and discrete geometry for energy-minimizing segmentation
Martin Braure De Calignon, Luc Brun, Jacques-Olivier Lachaud
This paper defines the basis of a new hierarchical framework for segmentation algorithms based on energy minimization schemes. This new framework is based on two formal tools. Firs…
Coding cells of digital spaces: a framework to write generic digital topology algorithms
Jacques-Olivier Lachaud
This paper proposes a concise coding of the cells of n-dimensional finite regular grids. It induces a simple, generic and efficient framework for implementing classical digital top…
Maximal digital straight segments and convergence of discrete geometric estimators
F. De Vieilleville, Jacques-Olivier Lachaud, F. Feschet
Discrete geometric estimators approach geometric quantities on digitized shapes without any knowledge of the continuous shape. A classical yet difficult problem is to show that an…
Revisiting Digital Straight Segment Recognition
F. De Vieilleville, Jacques-Olivier Lachaud
This paper presents new results about digital straight segments, their recognition and related properties. They come from the study of the arithmetically based recognition algorith…
