Image Analysis and Mathematical Morphology, Volume 1

From the Preface

Mathematical morphology used to be born in 1964 while G. Matheron used to be requested to enquire the relationships among the geometry of porous media and their permeabilities, and while while, i used to be requested to quantify the petrography of iron ores, as a way to expect their milling homes. This preliminary interval (1964-1968) has led to a primary physique of theoretical notions (Hit or omit changes, openings and closings, Boolean models), and in addition within the first prototype of the feel analyser. It was once additionally the time of the production of the Centre de Morphologie Mathematique at the campus of the Paris institution of Mines at Fontainebleau (France). primarily, the recent workforce had discovered its personal sort, made up of a symbiosis among theoretical learn, purposes and layout of units.

These have the subsequent proposal in universal: the suggestion of a geometric constitution, or texture, isn't basically goal. It doesn't exist within the phenomenon itself, nor within the observer, yet someplace in among the 2. Mathematical morphology quantifies this instinct by way of introducing the idea that of structuring components. selected via the morphologist, they have interaction with the item below examine, enhancing its form and· decreasing it to a kind of cartoon that is extra expressive than the particular preliminary phenomenon. the ability of the procedure, but additionally its trouble, lies during this structural sorting. certainly, the necessity for a normal thought for the principles of deformations seemed quickly. the tactic improved because of an interchange among highbrow intuitions and functional calls for coming from the functions. This ultimately bring about the content material of this publication. at the approach, numerous researchers joined the preliminary crew and constituted what's now known as the "Fontainebleau School". between them, we will quote J. C. Klein, P. Delfiner, H. Digabel, M. Gauthier, D. Jeulin, E. Kolomenski, Y. Sylvestre, Ch. Lantuejoul, F. Meyer and S. Beucher.

A new conception by no means seems via spontaneous iteration. It begins from a few preliminary wisdom and grows in a undeniable context. The genealogy of mathematical morphology primarily includes the 2 branches of fundamental geometry and geometrical chances, plus a number of collateral ancestors (harmonic research, stochastic procedures, algebraic topology). except mathematical morphology, 3 different parallel branches should be regarded as present descendants of an analogous tree. they're stereology, aspect tactics and stochastic geometry as constructed via D. G. Kendall's tuition at Cambridge. Stereology, in contrast to the opposite , is orientated in the direction of functions. The stereologists have succeeded in placing the most important theorems of vital geometry into perform. certainly their society regroups biologists and experts of the cloth sciences whose mutual curiosity lies within the quantitative description of buildings, mostly on the microscopic scale.

The different and more moderen department of "picture processing" seemed within the usa first and foremost of the Sixties because of the N. A. S. A. actions. this day, its scope has prolonged to domain names except satellite tv for pc imagery, its viewers has turn into extra foreign and is now represented via medical societies similar to that of trend acceptance. those scientists are regrouped extra through a typical category of difficulties (enhancement and segmentation of images, characteristic extraction, distant sensing) than by means of a selected method. the following, the theoretical instruments usually belong to the convolution and filtering equipment (Fourier, Karhuhen-Loeve and so on. ); additionally they use a few algorithms of mathematical morphology with no connecting them with the overall underlying notions. eventually, to a lesser volume, they borrow their strategies from syntactic and rest methods.

The final tree to which mathematical morphology belongs is that of photo analysers. it all started in 1951, while J. Von Neumann proposed an automated method which in comparison every one pixel with its rapid neighbours. over the last 20 years, approximately thirty prototypes of units were equipped for electronic photograph research. one of the few of them that have been commercialized, we will be able to quote the quantimets, in accordance with classical stereology, and the Leitz texture analyser, which was once the best-selling snapshot analyser on the finish of the 1970s.

The necessity to build a tool which can simply practice morphological operations on genuine specimens seemed very early in my paintings. i needed to layout an an identical of the pc for geometry, the place the hit and miss transformation and its derivatives might substitute the fundamental algebraic operations cabled within the traditional pcs. I known as this invention the feel analyser, and with an expanding participation of J. C. Klein, I equipped 4 prototypes among 1965 and 1975. The Wild-Leitz corporation obtained the licence in 1970 and presently produces this device, after having remodelled it for advertisement merchandising. even though the quasi-totality of the examples and of the pictures of this booklet come from texture analysers, i've got systematically shunned describing expertise and undefined.

Anyway, this actual approach, like several computing device elements, will quickly develop into out of date. The applied sciences will switch, yes particular exercises may be pre-programmed through microprocessors, the interior constitution may be made extra parallel, or extra pipelined, however the notion of the feel analyser will stay an identical. reason why, through the fundamental morphological operations, it hyperlinks the particular experiments to very basic must haves of the experimentation of geometrical structures.

Schematically, forty% of the cloth of this e-book has now not been released sooner than, one other forty% comes from works of the Fontainebleau tuition yet isn't continually popular, and the remaining comes from different resources. i've got set the extent of the booklet on the interface of purposes and thought, and feature emphasised the hyperlinks among modes of operation and normal underlying strategies. A entire set of natural mathematical effects are available in G. Matheron (I 975). I quote, with out proofs, his most crucial theorems.

This ebook is directed to the triple viewers of the clients of the strategy (biologists, metallographers, geologists, geographers of aerial imagery . .. ), the experts of photo processing and the theoreticians (probabilists, statisticians). those various different types of readers should not used to an analogous formalism, neither do they formulate their concepts in a typical language. as a result, I needed to discover a universal floor for the 3, which isn't a simple job. i am hoping the reader will excuse me if i haven't thoroughly succeeded. for instance, i've got refrained from utilizing programming languages or even circulation charts, who prefer to give the morphological notions in the extra common framework of set geometry. unusual phrases equivalent to "idempotence" or "antiextensivity" tend to surprise many naturalists; i do know this, yet their geometrical interpretations are so intuitive that each experimenter will quickly grab their meaning.

Apart from the language of mathematical morphology, its methodological deductions may possibly bewilder the reader used to a different conceptual historical past. maybe this trouble may be lessened if I make a number of reviews at the subject.

Mathematical morphology offers with units in Euclidean or electronic areas, and considers the capabilities outlined in an n-dimensional area as specific units of size n + l (classically, in photograph processing, the functionality is the first concept and the set is a selected case). To invert the concern among units and features leads us to stress the non-linear operations of sup and inf to the detriment of addition and subtraction.

Basically, the gadgets less than examine are regarded as being embedded within the ordinary Euclidean area; afterwards they're digitalized (in distinction to this, photo processing is largely digital). appropriate topologies then permit the robustness of the morphological operations to be studied. this could be very unlikely in a natural electronic framework, the place the reference of the Euclidean area is lacking. i do know that normal topology isn't really normal to nearly all of the readers, however it is the cost we need to pay for analysing the soundness, the standard, i. e. eventually the that means of the entire sensible algorithms.

As we've seen, the most aim of morphology is to bare the constitution of the items through remodeling the units which version them (such a goal generalizes that of necessary geometry and of stereology, which is composed of remodeling bounded units into major numbers). even though, ready alterations are usually not on the comparable point. Algorithms are ruled through extra common standards, which in tum fulfill a number of common constraints. a person wishing to grasp mathematical morphology needs to assimilate this vertical hierarchy (picture processing is incomparably extra "horizontal"). as a result, we didn't layout the e-book in line with a number of difficulties comparable to picture enhancement, filtering, or segmentation, yet on a category in accordance with standards and comparable questions. each morphological criterion may also help to section a picture, based upon the kind of snapshot and the preliminary wisdom of it that we own. it really is accurately this data which orients us in the direction of one or one other form of criteria.

A powerful counterpoint interlaces standards to versions. It regularly brings set types into play, however the creation of probabilistic notions opens the door to the extra particular type of random set types. this provides upward push to the 4 major elements of the e-book: theoretical instruments, partial wisdom, standards, random models.

This booklet might be learn in numerous other ways, based upon the sector of curiosity of the reader. The textual content itself is developed in a logical order the place each new concept is brought as regards to the previous notions and never to the subsequent ones. this sort of rule, obligatory whilst one writes a e-book, doesn't must be revered through the readers. an individual more often than not drawn to the algorithms and their experimental implementation may possibly begin with the 1st chapters and bounce on to the 4 chapters on standards. He may also pass over the theoretical sections integrated in those six chapters if he needs (i. e. bankruptcy II, part E; bankruptcy IX, part D; bankruptcy X, part F; bankruptcy XI, Sections B, C, D; bankruptcy XII, Sections B, G, H). the 1st interpreting will most likely encourage him to move extra. He can then pursue with the extra theoretical chapters, both these targeted on likelihood or then again these on geometry. may still he choose to stick to the way in which proposed for statisticians and probabilists, then the second one point includes Chapters V (parameters), VIII (sampling) and XIII (random sets). If he feels extra tempted through geometrical equipment, then we recommend yet another step including Chapters IV (convexity), VI and VII (digital morphology) and the theoretical enhances passed over within the first interpreting. ultimately, bankruptcy III is a evaluation of topological effects wanted essentially all around the e-book, and bankruptcy XIV, a nontechnical end.
