Fontainebleau. Comments about my
scientific work As a conclusion, I would
like to survey briefly the major themes of my scientific career, described
from a general perspective first, and then from a more personal point of
view. What is Mathematical Morphology ?
In the field of image processing, although matters evolve rapidly,
some methodological bases, some a priori points of view frow which one
tries to understand the physical world remain unchanged. As regards
Mathematical Morphology, this behaviour consists in favouring ordering
relations between regions rather than their metric characteristics. In
particular, it directly leads to set descriptors. Using this kind of
approach, as soon as one looks beyond the mathematical layer, a certain
epistemology arises. For instance, the Matheron’s axiomatics for a granulometry
summarises the essentials of all the techniques designed for measuring
size, and even of what is meant by the word "size". The same
applies to several other concepts, such as that of a connective criterion
for image segmentation [39].
The above choice requires some comments. In natural sciences,
morphological description precedes the determination of laws, whereas it
follows in physics. The main interest of a law comes classically from the
elimination of morphological characteristics (volume, etc). However, in many
areas, both the structural description and the determination of laws
coexist, and we must try to bring them together. In order to achieve this
goal Mathematical Morphology has conceived descriptors [1], and has developed
its theory along three ways. First, it proposes a set of operators expressing
some characteristics of the medium of the image under study (morphological
filters [3], connections [3][29][31], etc ). Here the background is that of
lattices, which allows to formalize ordering relations, suprema, etc..
and which turns out to be a
common denominator to sets, to numerical, or vector, functions and to
partitions. Second, Mathematical Morphology elaborates a comprehensive range
of random models [20][28], and third it achieves a synthesis between texture
and physical properties, at least in some fields of physics, such as
mechanics [12][14][15]. Although morphological operators were
initially set oriented and designed for physics, they have pursued their own
evolution, according to the addressed issues : a tool exists independently of
its initial finality. For three decades they have been extensively used in
optical or electron microscopy (cytology, histology [25], material sciences
[11][14]) and in the areas where numerical images are generated, such as
radiology or remote sensing. They have served also as a substitute for human
vision in various industrial tasks (quality control [16], security). But new
fields give rise to new theoretical issues and the boom of multimedia
applications during the last decade has led to original concepts (connection
[3][290][39], connected operators [26][27], geodesy [33][35]). It is worth quoting another event,
which occurred also during the
nineties. The International Society for Mathematical Morphology (ISMM) was
founded in 1993 in Barcelona, where the first international workshop on the
subject took place. Since this time, five other symposia were held. In
symbiosis with the activities of ISMM, the Pierre Soilles’s « morphological
digest », transmitted by Internet means, has an audience of one thousand
regular readers. But the number of the users of the method is incomparably
larger, and several morphological operators, such as openings, hitormiss,
etc.. are now everyday features in image processing. My voice
in the choir
In 1965, in cooperation with G. Matheron, I laid the
foundations of a new method, that we called Mathematical Morphology
[7][8][9], and we created the "Centre de Morphologie Mathématique"
within the Ecole des Mines de Paris three years later. The initial, and still
valid, purpose was to link physical properties with textures, in fluid
mechanics, sintering processes, etc... . First the supervisor of my PhD
thesis, Georges Matheron, who was ten years older than me, gradually became
my friend. Indeed, it is always difficult to situate one's work when it is
closely linked with a partner with whom one has been associated for
thirtyfive years, and who departed two years ago.
During the last decade however, our common activity
notably reduced. G. Matheron devoted his last efforts to the theory of
compact lattices (19901996). On my part, I clearly oriented the research of
the Centre de Morphologie Mathématique towards information related problems
(telecom, image and video compression, data retrieval, contentbased
indexing). These applications led me
to formulate the theory of morphological connections on lattices that
is the core curriculum for a comprehensive class of filters and segmentations
adapted to human vision. My
scientific activity during the period 19651985 is gather together in the two volumes of "Image Analysis
and Mathematical Morphology", Ac. Press
(Vol. I, 1982 ; Vol. II,
1988). As many scientists getting on in age, I am the author, or coauthor,
of more than one hundred papers, and about ten books. During the last twenty
years, my main contributions to mathematics and physics were the following 
The theory of morphological filtering, coinvented
with G. Matheron, in 19831998,
which constitutes an
alternative to Fourier analysis [3]; 
the formulation of
mathematical morphology in the framework of the complete lattices ( in
cooperation with G. Matheron , 19841988) [3] [19] [29] ; 
A study of the
equicontinuous functions, with a view to processing images (19911998) [22]
[28]; 
The concept of a connection,
that generalizes connectivity ; it was initially set up morphological
filtering (19882000), and that led on a theory of segmentation (20022004)
[39]; 
Some works on colour that
hold on new luminance/saturation/hue systems and on a physical model for
reflection/diffusion (20012004) [34][37][41]; 
A theory of interpolation
which is based on some geodesics of Hausdorff distance (19982000) [30][32]. I am fascinated by the process that makes the world
intelligible, and which, conversely, goes back from theory to an actual handling
of things. That is the reason why I designed and patented image analysers,
and why I launched several companies, for industrial control, for
fingerprints, for quantitative microscopy, and others. Texts most
