Morphological filtering on graphs

J Cousty, L Najman, F Dias, J Serra - Computer Vision and Image …, 2013 - Elsevier
We study some basic morphological operators acting on the lattice of all subgraphs of an
arbitrary (unweighted) graph G. To this end, we consider two dual adjunctions between the …

Morpho-logic from a topos perspective–application to symbolic AI

M Aiguier, I Bloch, S Nibouche, RP Pérez - International Journal of …, 2023 - Elsevier
Modal logics have proved useful for many reasoning tasks in symbolic artificial intelligence
(AI), such as belief revision, spatial reasoning, among others. On the other hand …

Mathematical morphology on hypergraphs, application to similarity and positive kernel

I Bloch, A Bretto - Computer vision and image understanding, 2013 - Elsevier
The focus of this article is to develop mathematical morphology on hypergraphs. To this aim,
we define lattice structures on hypergraphs on which we build mathematical morphology …

On morphological hierarchical representations for image processing and spatial data clustering

P Soille, L Najman - International Workshop on Applications of Discrete …, 2010 - Springer
Hierarchical data representations in the context of classification and data clustering were put
forward during the fifties. Recently, hierarchical image representations have gained …

A short tour of mathematical morphology on edge and vertex weighted graphs

L Najman, F Meyer - … and Analysis with Graphs: Theory and …, 2012 - api.taylorfrancis.com
Mathematical morphology is a discipline of image analysis that was introduced in the mid-
1960s by two researchers at the Ecole des Mines in Paris: Georges Matheron [1] and Jean …

[HTML][HTML] Robust similarity between hypergraphs based on valuations and mathematical morphology operators

I Bloch, A Bretto, A Leborgne - Discrete Applied Mathematics, 2015 - Elsevier
This article aims at connecting concepts of similarity, hypergraph and mathematical
morphology. We introduce new measures of similarity and study their relations with pseudo …

Similarity between hypergraphs based on mathematical morphology

I Bloch, A Bretto, A Leborgne - … Morphology and Its Applications to Signal …, 2013 - Springer
In the framework of structural representations for applications in image understanding, we
establish links between similarities, hypergraph theory and mathematical morphology. We …

Expressing discrete spatial relations under granularity

G Sindoni, K Sano, JG Stell - Journal of Logical and Algebraic Methods in …, 2021 - Elsevier
The logic UBiSKt is a bi-intuitionistic modal logic with universal modalities having a
semantics in which formulae are interpreted as subgraphs. We use the logic to formalize the …

Dimensional operators for mathematical morphology on simplicial complexes

F Dias, J Cousty, L Najman - Pattern Recognition Letters, 2014 - Elsevier
In this work we study the framework of mathematical morphology on simplicial complex
spaces. Simplicial complexes are widely used to represent multidimensional data, such as …
