Extraction of Connected Region Boundary in Multidimensional Images
Autor: David Coeurjolly, Bertrand Kerautret, Jacques-Olivier Lachaud
Publikováno v: Image Processing On Line, Vol 4, Pp 30-43 (2014)
This paper presents an algorithm to extract the boundary of a connected region(s) using classical topology definitions. From a given adjacency definition, the proposed method is able to extract the boundary of an object in a generic way, independentl

Many applications ranging from quasi-Monte Carlo integration over optimal control to neural networks benefit from high-dimensional, highly uniform samples. In the case of computer graphics, and more particularly in rendering, despite the need for uni

A New Lattice-based Plane-probing Algorithm
Autor: David Coeurjolly, Jui-Ting LU, Tristan Roussillon
Publikováno v: Lecture Notes in Computer Science ISBN: 9783031198960
Plane-probing algorithms have become fundamental tools to locally capture arithmetical and geometrical properties of digital surfaces (boundaries of a connected set of voxels), and especially normal vector information. On a digital plane, the overall

Publikováno v: ACM Transactions on Graphics
ACM Transactions on Graphics, Association for Computing Machinery, 2020, 39 (4), ⟨10.1145/3386569.3392413⟩
Being able to duplicate published research results is an important process of conducting research whether to build upon these findings or to compare with them. This process is called "replicability" when using the original authors' artifacts (e.g., c

Blue-noise sampling for human retinal cone spatial distribution modeling
Autor: Hélène Perrier, Alessandro Rizzi, M.P. Lanaro, Victor Ostromoukhov, David Coeurjolly
Publikováno v: Journal of Physics Communications
Journal of Physics Communications, IOP Publishing, 2020, 4 (3), pp.035013. ⟨10.1088/2399-6528/ab8064⟩
This paper proposes a novel method for modeling human retinal cone distribution. It is based on Blue-noise sampling algorithms that share interesting properties with the sampling performed by the mosaic formed by cone photoreceptors in the retina. He
