Mathematical Morphology Exercises With Mamba (solutions included) CMM/Mines ParisTech/Mamba-Image Publication, June 2016.

This document contains about fifty Mathematical Morphology exercises with their solutions using the Mamba Image library. This manual replaces the previous one where no solution was provided. These exercises address the following domains: basic notions, filtering, measure, residual operators, feature extraction, image segmentation.

Maxima and Minima: A Review CMM/Mines-ParisTech publication, September 2013.

The purpose of this document is just to provide additional information about the concepts of maxima and minima in MM. I have indeed noticed, when giving a class on the geodesic transforms, that these concepts were misleading. This paper must simply be considered as a clarification (I hope!) of these notions. Mamba implementations of the operators are also provided.

Basic Morphological Operators Applied On Partitions CMM/Mines-ParisTech publication, March 2013.

This document describes morphological operators designed for partitions (mosaic) images. Two approaches are addressed. Either each cell of the partition is processed independently of the other cells or the partition is considered as an image representation of a graph where some basic morphological operators (erosion and dilation) can be defined. A fast implementation of these operators in the Mamba image library is also given.

Towards a unification of waterfalls, standard and P algorithms CMM/Mines ParisTech publication, January 2012.

This document is an extension of the paper: P algorithm, a dramatic enhancement of the waterfall transformation (see below). It has mainly two purposes. Firstly, it comes back to the waterfalls, standard and P algorithms to propose a general segmentation scheme which covers and unifies these different processes. Secondly, it contains the source code for the implementation of these waterfalls, standard and P operators with the MAMBA Image software library.

About a problem of definition of the geodesic erosion CMM/Mines ParisTech publication, September 2011.

This note is the english translation of the paper: Sur un problème de définition de l'érosion géodésique (see below).

How to simulate a volume-controlled flooding with mathematical morphology operators? CMM/Mines ParisTech publication, November 2011.

This note discusses some ideas for simulating a (real) flood on a (real) topographic surface by means of morphological tools. This work has been initiated following exchanges with some partners of the THESEUS project (Innovative technologies for safer European coasts in a changing climate) regarding the use of mathematical morphology tools for flooding simulations

(note that the CMM does not belong to the THESEUS consortium, this contribution has no other motive than promoting morphological tools in this research domain!).

This note (in french, see the english translation above) addresses a problem of definition of the geodesic erosion in the numerical case. It shows that the binary geodesic erosion does not correspond to the definition currently used in the numerical case. It also defines a new numerical geodesic erosion which really extends the binary operator. Update (october 2011): two annexes have been added, the first one describing all the new geodesic elementary operators and the second one containing the sources of these new operators for the MAMBA library (these operators are available for the version 1.1.1 but they can be easily upgraded to the current version).

Hierarchical Queues: general description and implementation in MAMBA Image library

[co-author Nicolas Beucher], www.mamba-image.org/CMM/Mines ParisTech publication, April 2011.

This paper describes thoroughly the hierarchical queues (HQ) which are implemented in the MAMBA image library. The use of these HQ to realize watershed transforms and geodesic reconstructions is fully explained. The extension of these morphological operators to 32-bit images is also described.

Fast implementation of large erosions and dilations in Mamba CMM/Mines ParisTech publication, October 2010.

This document explains how to implement fast erosions and dilations when large structuring elements are needed. These structuring elements can be squares, hexagons, octogons or dodecagons. This implementation, realized in the Mamba library brings a dramatic increase of the computation speed. This increase is all the more important as the size of the structuring element is large.

P algorithm, a dramatic enhancement of the waterfall transformation.

[co-author Beatriz Marcotegui], CMM/Mines Paristech publication, 86 pages. September 2009.

This document describes an efficient enhancement of the waterfall algorithm, a hierarchical segmentation algorithm defined from the watershed transformation. The first part of the document recalls the definition of the waterfall algorithm, its various avatars as well as its links with the geodesic reconstruction. The second part starts by analyzing the different shortcomings of the algorithm and introduces several strategies to palliate them. Two enhancements are presented, the first one named standard algorithm and the second one, P algorithm. The different properties of P algorithm are analyzed. This analysis is detailed in the last part of the document. The performances of the two algorithms, in particular, are addressed and their analogies with perception mechanisms linked to the brightness constancy phenomenon are discussed. An oral presentation of this paper (in french) can be found here.

This report (released in february 1989) describes the various algorithms which have been used to analyse electrical logging images. This report introduces many tools which can be found also in my PhD thesis. Among them, various types of morphological gradients, operators using the generalised geodesic distance and new residual operators, in particular ultimate openings (directional ultimate openings).

This document addresses different approaches for the parallelisation of the watershed transform by hierarchical queues. This study was performed in 1997 (for the former THOMSON company) but this algorithmic implementation remains an issue. You may also have a look at this paper where the watershed parallelisation is briefly discussed again.

This document describes the algorithms implemented in the TITAN traffic measurement system (research project realised in collaboration with INRETS in 1986-1987). Many new concepts and algorithms were introduced during this project. Among them, the concept of adaptive algorithms and the notion of extended maxima and minima.

These two reports illustrate the first use of the watershed transformation for segmenting images (stereo pairs to be specific). The problem was far from being simple.

This document describes the implementation of some morphological operators on the Wild Leitz TAS (Texture Analysis System). The ultimate erosion, in particular, is explained. This operator largely contributed to the commercial success of the TAS.
