Available in PDF, EPUB and Kindle. Book excerpt: La reconnaissance de formes planes partiellement masquées ne peut se faire que localement en calculant des points caractéristiques (extrema de courbure, points d'inflexions,), et ce calcul requiert un procédé de lissage des formes. Si l'on veut effectuer cette reconnaissance modulo toutes les déformations affines du plan, alors ce procédé est unique : c'est le scale space affiné, découvert en 1993, qui peut être décrit par une équation d'évolution. Dans la première partie de cette thèse, nous montrons comment résoudre cette équation numériquement avec précision, en itérant un opérateur continu, géométrique, global et exactement calculable. Des propriétés de consistance forte et de convergence sont établies et validées par de nombreuses expériences numériques. Ce procédé surpasse largement les schémas classiques aux différences finies, qui ne peuvent vérifier rigoureusement l'invariance affine et le principe d'inclusion. Dans une deuxième partie, nous étudions l'un des problèmes fondamentaux de la robotique, la reconstruction du relief à partir d'une séquence d'images. Il s'avère que lorsque le mouvement de l'observateur peut être déterminé, il n'existe fondamentalement qu'une seule manière de filtrer la séquence d'images tout en préservant le relief sous-jacent. Ce filtrage, obtenu grâce à une démarche axiomatique, se formule par une équation aux dérivées partielles non linéaire du second ordre, parabolique dégénérée, qui présente une singularité très forte inhérente au problème de reconstruction. Nous établissons des resultats d'existence et d'unicité pour cette équation, puis mettons en évidence certaines propriétés mathématiques qui se prêtent facilement à une interprétation physique. Enfin, nous décrivons un schéma numérique adapté, et réalisons des expériences qui montrent que ce filtrage, par la cohérence qu'il induit, ramène le procédé de reconstruction à un calcul élémentaire et fiable.

Book Synopsis Partial Differential Equations by : J. Necas
Download or read book Partial Differential Equations written by J. Necas and published by Routledge. This book was released on 2018-05-04 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a satellite conference of the 1998 International Mathematical Congress and part of the celebration of the 650th anniversary of Charles University, the Partial Differential Equations Theory and Numerical Solution conference was held in Prague in August, 1998. With its rich scientific program, the conference provided an opportunity for almost 200 participants to gather and discuss emerging directions and recent developments in partial differential equations (PDEs). This volume comprises the Proceedings of that conference. In it, leading specialists in partial differential equations, calculus of variations, and numerical analysis present up-to-date results, applications, and advances in numerical methods in their fields. Conference organizers chose the contributors to bring together the scientists best able to present a complex view of problems, starting from the modeling, passing through the mathematical treatment, and ending with numerical realization. The applications discussed include fluid dynamics, semiconductor technology, image analysis, motion analysis, and optimal control. The importance and quantity of research carried out around the world in this field makes it imperative for researchers, applied mathematicians, physicists and engineers to keep up with the latest developments. With its panel of international contributors and survey of the recent ramifications of theory, applications, and numerical methods, Partial Differential Equations: Theory and Numerical Solution provides a convenient means to that end.

Book Synopsis Introduction au traitement mathématique des images - méthodes déterministes by : Maïtine Bergounioux
Download or read book Introduction au traitement mathématique des images - méthodes déterministes written by Maïtine Bergounioux and published by Springer. This book was released on 2015-02-20 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce cours est une introduction au traitement d'image mathématique déterministe. Les principales problématiques en traitement et analyse d’image y sont présentées: débruitage/filtrage/restauration, segmentation, rehaussement/défloutage, ainsi qu’un aperçu de quelques techniques d’acquisition. Les méthodes mathématiques utilisées ont essentiellement déterministes : transformation de Fourier, ondelettes, équations aux dérivées partielles, morphologie mathématique et méthodes variationnelles. Quelques applications y sont brièvement présentées pour illustrer le propos : la stéganographie, la compression et l’inpainting (ou désocclusion). Le livre comprend également un rappel des principales notions mathématiques utilisées (il se veut auto-suffisant) et la bibliographie abondante doit permettre au lecteur d’approfondir les techniques qui l’intéressent. Cet ouvrage s’adresse à des étudiants de MASTER, élèves-ingénieurs ou chercheurs désireux de comprendre ou d’approfondir les techniques mathématiques de base en traitement et analyse d’image. This course is an introduction to deterministic mathematical image processing. The main issues in processing and image analysis are presented: denoising, filtering, restoration, segmentation, enhancement and deblurring.There is also an overview of some acquisition techniques. Mathematical methods are essentially deterministic: Fourier transform, wavelets, partial differential equations, mathematical morphology and variational methods. Some applications are briefly presented to illustrate the topic, such as steganography, compression and inpainting. This self-contained book also includes a recap of the basic mathematical concepts used, and the extensive bibliography will enable readers to develop their skills. This book is intended for masters students, engineering students and researchers wanting to comprehend or deepen their understanding of thebasic mathematical techniques in processing and image analysis.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans cette thèse, nous nous intéressons aux équations aux dérivées fractionnaires et leurs applications au traitement d'images. Une attention particulière a été apportée à un système non linéaire d'équations différentielles fractionnaires. En particulier, nous avons étudié les propriétés qualitatives des solutions d'un système non linéaire d'équations différentielles fractionnaires qui explosent en temps fini. L'existence des solutions locales pour le système, le profil des solutions qui explosent en temps fini sont présentés. Nous étudierons le problème inverse pour l'équation de diffusion linéaire en une dimension et en deux dimensions. Nous sommes intéressés par trouver un terme source inconnu d'une équation de diffusion non locale. Les conditions aux limites considérées sont non locales et le problème spectral est non auto-adjoint. L'existence et l'unicité de la solution du problème inverse sont présentées.D'autre part, nous proposons un modèle basé sur l'équation de la chaleur linéaire avec une dérivée fractionnaire en temps pour le débruitage d'images numériques. L'approche utilise une technique de pixel par pixel, ce qui détermine la nature du filtre. En contraste avec certain modèles basés sur les équations aux dérivées partielles pour le débruitage de l'image, le modèle proposé est bien posé et le schéma numérique est convergent. Une amélioration de notre modèle proposé est suggéré.
