This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'affichage en relief, avec ou sans lunettes, est de plus en plus populaire. Les écrans auto-stéréoscopiques comportent un nombre d'images compris, à ce jour, entre 2 et 9. La création, la transmission ou encore la diffusion d'un tel nombre d'images correspondent à autant de verrous scientifiques. En effet la transmission des images impose le développement de méthodes de compression qui exploitent la redondance d'information entre les vues. La diffusion nécessite qu'un même contenu puisse être visible sur un maximum d'écrans, ce qui n'est possible en pratique que grâce à des méthodes de synthèse de vues intermédiaires. Enfin le contexte multi-vues ouvre à de nouvelles perspectives en réalité augmentée, comme la projection d'ombres et l'occultation entre contenu réel et virtuel. Tous ces exemples ont pour point commun de pouvoir être obtenus par le calcul des profondeurs de la scène. Les méthodes de stéréovision sont donc incontournables, mais, génériques, elles ne sont adaptées ni au contexte multi-vues, ni aux besoins des applications citées précédemment. Nous proposons dans ce mémoire un pipeline de reconstruction des profondeurs dédié au contexte multi-vues. Au travers d'une nouvelle expression de la mise en correspondance multi-vues, qui consiste à regrouper les pixels représentant un même point de la scène en " match " et ainsi former un partitionnement de l'ensemble des pixels, notre pipeline tire profit de la redondance des informations afin d'obtenir une estimation robuste des profondeurs. Cette expression définit exactement les redondances et occlusions de la scène, ce qui lève une grande partie des ambiguïtés lors de la compression des images et de la synthèse de vues intermédiaires. Nous présentons également une nouvelle contrainte, intégrée à notre pipeline, qui assure la cohérence géométrique des profondeurs reconstruites. Cette contrainte, essentielle pour un mélange entre réel et virtuel cohérent, s'avère également très utile pour les méthodes de synthèse de vues intermédiaires. Notre pipeline est composé de quatre modules : " génération du nuage de points ", " reconstruction de la surface ", " affinement des profondeurs " et " suivi temporel ". Mis à part le premier module cité, les autres sont facultatifs, et leur utilisation dépend des besoins et des applications visées. Ainsi, les résultats de notre pipeline sont les cartes de profondeurs, un nuage de points, ou un maillage représentant la scène.Afin de prouver la faisabilité du pipeline, nous présentons deux implémentations de celui-ci.La première, dite locale, se base sur des méthodes rapides afin de reconstruire la scène en temps réel. La seconde implémentation vise une application en post-production et génère des profondeurs de meilleure qualité, au détriment de temps de calcul plus longs. Nous démontrons également la pertinence de notre pipeline en proposant de nouvelles méthodes de compression d'images multi-vues, de synthèse de vues intermédiaires et de réalité augmentée multi-vues.
Download or read book Multi scale Feature Preserving Smoothing of Images and Volumes on GPU written by Nassim Jibai and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les images et données volumiques sont devenues importantes dans notre vie quotidienne que ce soit sur le plan artistique, culturel, ou scientifique. Les données volumiques ont un intérêt important dans l'imagerie médicale, l'ingénierie, et l'analyse du patrimoine culturel. Ils sont créées en utilisant la reconstruction tomographique, une technique qui combine une large série de scans 2D capturés de plusieur points de vue. Chaque scan 2D est obtenu par des methodes de rayonnement : Rayons X pour les scanners CT, ondes radiofréquences pour les IRM, annihilation électron-positron pour les PET scans, etc. L'acquisition des images et données volumique est influencée par le bruit provoqué par différents facteurs. Le bruit dans les images peut être causée par un manque d'éclairage, des défauts électroniques, faible dose de rayonnement, et un mauvais positionnement de l'outil ou de l'objet. Le bruit dans les données volumique peut aussi provenir d'une variété de sources : le nombre limité de points de vue, le manque de sensibilité dans les capteurs, des contrastes élevé, les algorithmes de reconstruction employés, etc. L'acquisition de données non bruitée est iréalisable. Alors, il est souhaitable de réduire ou d'éliminer le bruit le plus tôt possible dans le pipeline. La suppression du bruit tout en préservant les caractéristiques fortes d'une image ou d'un objet volumique reste une tâche difficile. Nous proposons une méthode multi-échelle pour lisser des images 2D et des données tomographiques 3D tout en préservant les caractéristiques à l'échelle spécifiée. Notre algorithme est contrôlé par un seul paramètre - la taille des caractéristiques qui doivent être préservées. Toute variation qui est plus petite que l'échelle spécifiée est traitée comme bruit et lissée, tandis que les discontinuités telles que des coins, des bords et des détails à plus grande échelle sont conservés. Nous démontrons les données lissées produites par notre algorithme permettent d'obtenir des images nettes et des iso-surfaces plus propres. Nous comparons nos résultats avec ceux des methodes précédentes. Notre méthode est inspirée par la diffusion anisotrope. Nous calculons nos tenseurs de diffusion à partir des histogrammes continues locaux de gradients autour de chaque pixel dans les images et autour de chaque voxel dans des volumes. Comme notre méthode de lissage fonctionne entièrement sur GPU, il est extrêmement rapide.

Download or read book Agricultural English written by Georgeta Raţă and published by Cambridge Scholars Publishing. This book was released on 2012-04-25 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural English is a collection of essays on the English of Agriculture. The approach is a linguistic one: the different aspects of the English used in the field of agriculture (agricultural practices, agricultural systems) and in some fields related to agriculture (agricultural zoology, agri-tourism, biology, botany, ecology, entomology, gastronomy, land measurement, plant pathology, zoology) are analysed from a morphological (combination, derivation), syntactical (nominal phrases, verbal phrases), lexical and lexicographical, semantic (homonymy, semantic fields, synonymy, terminology), pragmatic (academic discourse, idiom, metaphor), etymological (etymon, Latin heritage), and contrastive (English–Croatian, English–French, English–German, English–Romanian, Romanian–English) points of view. The book will appeal to agriculturists, animal breeders, professors, researchers, students, and translators from Croatian-, English-, French-, German-, and Romanian-speaking countries, active in their own countries or abroad. The types of academic readership it would appeal to include academic teaching staff, researchers and students in the fields of agriculture and related fields – agricultural zoology, agri-tourism, biology, botany, ecology, entomology, gastronomy, land measurement, plant pathology, and zoology.

Download or read book Unsettled Scores written by Sally Bick and published by University of Illinois Press. This book was released on 2019-12-20 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hollywood careers of Aaron Copland and Hanns Eisler brought the composers and their high art sensibility into direct conflict with the premier producer of America's potent mass culture. Drawn by Hollywood's potential to reach—and edify—the public, Copland and Eisler expertly wove sophisticated musical ideas into Hollywood and, each in their own distinctive way, left an indelible mark on movie history. Sally Bick's dual study of Copland and Eisler pairs interpretations of their writings on film composing with a close examination of their first Hollywood projects: Copland's music for Of Mice and Men and Eisler's score for Hangmen Also Die! Bick illuminates the different ways the composers treated a film score as means of expressing their political ideas on society, capitalism, and the human condition. She also delves into Copland's and Eisler's often conflicted attempts to adapt their music to fit Hollywood's commercial demands, an enterprise that took place even as they wrote hostile critiques of the film industry.
Download or read book Popular Music and the New Auteur written by Arved Ashby and published by Oxford University Press. This book was released on 2013-10-30 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: MTV utterly changed the movies. Since music television arrived some 30 years ago, music videos have introduced filmmakers to a new creative vocabulary: speeds of events changed, and performance and mood came to dominate over traditional narrative storytelling. Popular Music and the New Auteur charts the impact of music videos on seven visionary directors: Martin Scorsese, Sofia Coppola, David Lynch, Wong Kar-Wai, the Coen brothers, Quentin Tarantino, and Wes Anderson. These filmmakers demonstrate a fresh kind of cinematic musicality by writing against pop songs rather than against script, and allowing popular music a determining role in narrative, imagery, and style. Featuring important new theoretical work by some of the most provocative writers in the area today, Popular Music and the New Auteur will be required reading for all who study film music and sound. It will be particularly relevant for readers in popular music studies, and its intervention in the ongoing debate on auteurism will make it necessary reading in film studies.
Download or read book Theories of the Soundtrack written by James Buhler and published by . This book was released on 2019 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theory of the soundtrack is concerned with what belongs to the soundtrack, how a soundtrack is effectively organized, how its status in a multimedia object affects the nature of the object, the tools available for its analysis, and the interpretive regime that the theory mandates for determining the meaning, sense, and structure that sound and music bring to film and other audiovisual media. Beyond that, a theory may also delineate the range of possible uses of sound and music, classify the types of relations that films have used for image and sound, identify the central problems, and reflect on and describe effective uses of sound in film. This book summarizes and critiques major theories of the soundtrack from roughly 1929 until today. Rather than providing an exhaustive historical survey, it sketches out the range of theoretical approaches that have been applied to the soundtrack since the commercial introduction of the sound film. The basic theoretical framework of each approach is presented, taking into account the explicit and implicit claims about the soundtrack and its relation to other theories. The organization is both chronological and topical, the former in that the chapters move steadily from early film theory through models of the classical system to more recent critical theories; the latter in that the chapters highlight central issues for each generation: the problem of film itself, then of image and sound, of adequate analytical-descriptive models, and finally of critical-interpretative models.
Download or read book Film Music Analysis written by Emilio Audissino and published by Springer. This book was released on 2017-10-14 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an approach to film music in which music and visuals are seen as equal players in the game. The field of Film-Music Studies has been increasingly dominated by musicologists and this book brings the discipline back squarely into the domain of Film Studies. Blending Neoformalism with Gestalt Psychology and Leonard B. Meyer's musicology, this study treats music as a cinematic element and offers scholars and students of both music and film a set of tools to help them analyse the wide ranging impact that music has in films.
Download or read book Cinesonidos written by Jacqueline Avila and published by Oxford University Press. This book was released on 2019-09-16 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: During Mexico's silent (1896-1930) and early sound (1931-52) periods, cinema saw the development of five significant genres: the prostitute melodrama (including the cabaretera subgenre), the indigenista film (on indigenous themes or topics), the cine de añoranza porfiriana (films of Porfirian nostalgia), the Revolution film, and the comedia ranchera (ranch comedy). In this book, author Jacqueline Avila looks at examples from all genres, exploring the ways that the popular, regional, and orchestral music in these films contributed to the creation of tropes and archetypes now central to Mexican cultural nationalism. Integrating primary source material--including newspaper articles, advertisements, films--with film music studies, sound studies, and Mexican film and cultural history, Avila examines how these tropes and archetypes mirrored changing perceptions of mexicanidad manufactured by the State and popular and transnational culture. As she shows, several social and political agencies were heavily invested in creating a unified national identity in an attempt to merge the previously fragmented populace as a result of the Revolution. The commercial medium of film became an important tool to acquaint a diverse urban audience with the nuances of Mexican national identity, and music played an essential and persuasive role in the process. In this heterogeneous environment, cinema and its music continuously reshaped the contested, fluctuating space of Mexican identity, functioning both as a sign and symptom of social and political change.

Download or read book Music in the Shadows written by Sheri Chinen Biesen and published by JHU Press. This book was released on 2014-05 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Welcome to the world of noir musical films, where tormented antiheroes and hard-boiled musicians battle obsession and struggle with their music and ill-fated love triangles. Sultry divas dance and sing the blues in shrouded nightclubs. Romantic intrigue clashes with backstage careers. This book explores musical films that use film noir style and bluesy strains of jazz to inhabit a disturbing underworld and reveal the dark side of fame and the American Dream. While noir musical films like A Star Is Born include musical performances, their bleak tone and expressionistic aesthetic more closely resemble the visual style of film noir. Their narratives unfold behind a stark noir lens: distorted, erratic angles and imbalanced hand-held shots allow the audience to experience a tortured, disillusioned perspective. While many musicals glamorize the quest for the spotlight in Hollywood's star factory, brooding noir musical films such as Blues in the Night, Gilda, The Red Shoes, West Side Story, and Round Midnight stretch the boundaries of film noir and the musical as film genres collide. Deep shadows, dim lighting and visual composition evoke moodiness, cynicism, pessimism, and subjective psychological points of view.
Download or read book John Williams s Film Music written by Emilio Audissino and published by University of Wisconsin Pres. This book was released on 2014-06-12 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: John Williams is one of the most renowned film composers in history. He has penned unforgettable scores for Star Wars, the Indiana Jones series, E.T. the Extra-Terrestrial, Jaws, Superman, and countless other films. Fans flock to his many concerts, and with forty-nine Academy Award nominations as of 2014, he is the second-most Oscar-nominated person after Walt Disney. Yet despite such critical acclaim and prestige, this is the first book in English on Williams’s work and career. Combining accessible writing with thorough scholarship, and rigorous historical accounts with insightful readings, John Williams’s Film Music explores why Williams is so important to the history of film music. Beginning with an overview of music from Hollywood’s Golden Age (1933–58), Emilio Audissino traces the turning points of Williams’s career and articulates how he revived the classical Hollywood musical style. This book charts each landmark of this musical restoration, with special attention to the scores for Jaws and Star Wars, Williams’s work as conductor of the Boston Pops Orchestra, and a full film/music analysis of Raiders of the Lost Ark. The result is a precise, enlightening definition of Williams’s “neoclassicism” and a grounded demonstration of his lasting importance, for both his compositions and his historical role in restoring part of the Hollywood tradition.
