Available in PDF, EPUB and Kindle. Book excerpt: CE MEMOIRE DE THESE PRESENTE UNE METHODE DE SEGMENTATION ET DE SUIVI TEMPOREL DE SEQUENCES D'IMAGES. LA METHODE QUE NOUS PROPOSONS PERMET D'OBTENIR D'UNE PART L'ENSEMBLE DES SEGMENTATIONS SPATIALES ASSOCIEES A CHACUNE DES IMAGES DE LA SEQUENCE ET, D'AUTRE PART, UN SUIVI TEMPOREL DE POINTS CARACTERISTIQUES FOURNIS PAR LA SEGMENTATION. LE PROCEDE DE SUIVI TEMPOREL DE LA SEGMENTATION SPATIALE PEUT SE DECOMPOSER EN TROIS GRANDES PHASES: LA PHASE DE PREDICTION, LA PHASE DE MISE EN CORRESPONDANCE ET LA PHASE D'AFFINAGE. LA PHASE DE PREDICTION PERMET LE CALCUL D'UNE PREDICTION DE LA POSITION DE CHACUN DES POINTS CARACTERISTIQUES DANS L'IMAGE SUIVANTE, POSITION QUE L'ON DETERMINE DE FACON PRECISE LORS DE LA PHASE DE MISE EN CORRESPONDANCE. CETTE MISE EN CORRESPONDANCE EST EFFECTUEE DE FACON HIERARCHIQUE DANS UNE PREMIERE ETAPE PAR UNE PROCEDURE DETERMINISTE PUIS, DANS UNE SECONDE ETAPE, PAR UNE METHODE DE RELAXATION PROBABILISTE. ENFIN, LORS DE LA DERNIERE PHASE QUI RESTE A METTRE AU POINT, LA SEGMENTATION OBTENUE EST AJUSTEE AFIN DE RESTER EN PARFAITE COHERENCE AVEC LES SEGMENTATIONS PRECEDENTES

This book was released on 1998 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: CETTE THESE DECRIT PLUSIEURS METHODES PERMETTANT D'EXTRAIRE AVEC PRECISION LES OBJETS CONTENUS DANS LES SEQUENCES VIDEO. CHAQUE OBJET EST REPRESENTE PAR UN MODELE DE FORME POLYGONALE, PAR UN VECTEUR DE PARAMETRES DE MOUVEMENT AFFINE MAIS AUSSI PAR SA PROFONDEUR RELATIVE VIS-A-VIS DE SES OBJETS VOISINS. UNE MODELISATION 2D1/2 + T DE LA VIDEO EST DE CETTE MANIERE REALISEE. POUR PERMETTRE UNE CERTAINE GENERICITE DE LA REPRESENTATION VIS-A-VIS DES APPLICATIONS DIVERSES DU TRAITEMENT DES IMAGES, DANS UNE PREMIERE PHASE, UNE HIERARCHIE DE SEGMENTATIONS EST ETABLIE, BASEE SUR LE MOUVEMENT. CECI SIGNIFIE QUE POUR UNE MEME IMAGE, UN ENSEMBLE CONTINU ET EMBOITE DE SEGMENTATIONS EST CONSTRUIT. POUR CONSTRUIRE CES SEGMENTATIONS, UNE METHODE COOPERATIVE DE SEGMENTATION HIERARCHIQUE A ETE DEVELOPPEE DANS CETTE THESE. A PARTIR D'UNE SEGMENTATION SPATIALE D'UNE PART ET D'UNE SEGMENTATION GLOBALE D'AUTRE PART, UNE FUSION HIERARCHIQUE ASCENDANTE BASEE SUR L'ANALYSE DU MOUVEMENT REALISE LA FUSION ENTRE CES DEUX POINTS DE VUE. CETTE REPRESENTATION HIERARCHIQUE ET GENERIQUE PERMET DE VISER DES APPLICATIONS DE MANIPULATION D'OBJETS OU DE CODAGE A TAUX DE COMPRESSION VARIABLE EN FONCTION DU DEBIT DISPONIBLE OU DE LA QUALITE DESIREE. DANS UN SECOND TEMPS, UNE EXTRACTION DE L'INFORMATION DE PROFONDEUR RELATIVE DES OBJETS EN MOUVEMENT EST REALISEE. C'EST A PARTIR DE L'ANALYSE DES OCCULTATIONS DE CHACUN D'EUX QUE LE TRAITEMENT EST FAIT. CHAQUE OBJET A AINSI UNE INDEPENDANCE VIS-A-VIS DE SON VOISINAGE. CETTE INFORMATION DE PROFONDEUR EST ENSUITE UTILISEE DE SORTE A AMELIORER LES ALGORITHMES DE SUIVI TEMPOREL D'OBJETS. LA QUALITE DE LA PREDICTION DE LA SEGMENTATION DES OBJETS EN EST MEILLEURE ET PEUT SERVIR AUSSI A L'INTERPOLATION D'IMAGES. CES METHODES ONT ETE VALIDEES SUR UN ENSEMBLE DE SEQUENCES UTILISEES POUR LES TESTS ISO-MPEG IV.

Download or read book Terra 2008 written by Leslie Rainer and published by Getty Publications. This book was released on 2011-06-14 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.
Download or read book Botticelli Past and Present written by Ana Debenedetti and published by UCL Press. This book was released on 2019-01-08 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent exhibitions dedicated to Botticelli around the world show, more than ever, the significant and continued debate about the artist. Botticelli Past and Present engages with this debate. The book comprises four thematic parts, spanning four centuries of Botticelli’s artistic fame and reception from the fifteenth century. Each part comprises a number of essays and includes a short introduction which positions them within the wider scholarly literature on Botticelli. The parts are organised chronologically beginning with discussion of the artist and his working practice in his own time, moving onto the progressive rediscovery of his work from the late eighteenth to the turn of the twentieth century, through to his enduring impact on contemporary art and design. Expertly written by researchers and eminent art historians and richly illustrated throughout, the broad range of essays in this book make a valuable contribution to Botticelli studies.

Available in PDF, EPUB and Kindle. Book excerpt: This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center.
