Book Description
1.0 2 The attention then turned to the problem of "Body separation", i.e. separation of occluding bodies in a scene (See [Guzman), [Falk), and [Waltz)). Grape ([Grape)) combined the separation of bodies with recognition, by removing parts of the scene recognized as belonging to a known body. All of these techniques were designed to work with polyhedral objects only, and extensively use the properties of edges and vertices. Though some impressive results have been reported ([Waltz], [Grape)), and perhaps some useful abstractions can be made, the specific techniques used fail to generalize to a wider class of objects. Among previous work on curved objects, B.K.P. Horn ([Horn)) presented techniques for extracting three dimensional depth data from a TV image, using reflection characteristics of the surface. Krakauer ([Krakauer]) represented objects by connections of brightness contours. Ambler et al ([Ambler)) describe experiments with simple shapes, including curved objects, using relations within a two-dimensional image. However, none of these efforts really addresses the problem of "shape" representation and description. Work on outdoor scene analysis is also concerned with non-polyhedral objects ([Bajcsy], [Yakimovsky]), but again no attention has been paid to shape analysis.

Book Description
How does a visual artist manage to narrate a story, which has a sequential and therefore temporal progression, using a static medium consisting solely of spatial sign elements and, what is more, in a single image? This is the question on which this work is based, posed by its designer, Alberto Argenton, to whose memory it is dedicated. The first explanation usually given by scholars in the field is that the artist solves the problem by depicting the same character in a number of scenes, thus giving indirect evidence of events taking place at different times. This book shows that artists, in addition to the repetition of characters, devise other spatial perceptual-representational strategies for organising the episodes that constitute a story and, therefore, showing time. Resorting to the psychology of art of a Gestalt matrix, the book offers researchers, graduates, advanced undergraduates, and professionals a description of a large continuous pictorial narrative repertoire (1000 works) and an in-depth analysis of the perceptual-representational strategies employed by artists from the 6th to the 17th century in a group of 100 works narrating the story of Adam and Eve.

Book Description
Most video and film editors understand that the story is central to their work and that editing choices need to serve the telling of that story in the best way possible. What they may not know, however, are all the valuable techniques to making this craft appear seamless and part of the busy editor's normal workflow. This book takes an approach to editing that both beginners and intermediate editors will find refreshing. While other books approach the topic of editing by teaching the functions of the editing software, this book explains how you can make smart choices and use those functions to affect the story. In the book you'll learn workflow tips, time saving techniques, linear and non-linear theory, cutting techniques, enhancing emotion through music and sound effects, leveling and mastering audio, color correction, and most importantly, the role editing can have on the telling of the story. Additional techniques are shown through multiple step-by-step videos available on the author's site as well as clips from a documentary the author created on editing.

Book Description
This book presents computational methods for extracting the useful information from audio signals, collecting the state of the art in the field of sound event and scene analysis. The authors cover the entire procedure for developing such methods, ranging from data acquisition and labeling, through the design of taxonomies used in the systems, to signal processing methods for feature extraction and machine learning methods for sound recognition. The book also covers advanced techniques for dealing with environmental variation and multiple overlapping sound sources, and taking advantage of multiple microphones or other modalities. The book gives examples of usage scenarios in large media databases, acoustic monitoring, bioacoustics, and context-aware devices. Graphical illustrations of sound signals and their spectrographic representations are presented, as well as block diagrams and pseudocode of algorithms.

Book Description
Most designers know that yellow text presented against a blue background reads clearly and easily, but how many can explain why, and what really are the best ways to help others and ourselves clearly see key patterns in a bunch of data? When we use software, access a website, or view business or scientific graphics, our understanding is greatly enhanced or impeded by the way the information is presented. This book explores the art and science of why we see objects the way we do. Based on the science of perception and vision, the author presents the key principles at work for a wide range of applications--resulting in visualization of improved clarity, utility, and persuasiveness. The book offers practical guidelines that can be applied by anyone: interaction designers, graphic designers of all kinds (including web designers), data miners, and financial analysts. - Complete update of the recognized source in industry, research, and academic for applicable guidance on information visualizing - Includes the latest research and state of the art information on multimedia presentation - More than 160 explicit design guidelines based on vision science - A new final chapter that explains the process of visual thinking and how visualizations help us to think about problems - Packed with over 400 informative full color illustrations, which are key to understanding of the subject

Book Description
Through the eventful life of a Himalayan Buddhist teacher, Khunu Lama, this study reimagines cultural continuity beyond the binary of traditional and modern. In the early twentieth century, Khunu Lama journeyed across Tibet and India, meeting Buddhist masters while sometimes living, so his students say, on cold porridge and water. Yet this elusive wandering renunciant became a revered teacher of the Fourteenth Dalai Lama. At Khunu Lama’s death in 1977, he was mourned by Himalayan nuns, Tibetan lamas, and American meditators alike. The many surviving stories about him reveal significant dimensions of Tibetan Buddhism, shedding new light on questions of religious affect and memory that reimagines cultural continuity beyond the binary of traditional and modern. In Renunciation and Longing, Annabella Pitkin explores devotion, renunciation, and the teacher-student lineage relationship as resources for understanding Tibetan Buddhist approaches to modernity. By examining narrative accounts of the life of a remarkable twentieth-century Himalayan Buddhist and focusing on his remembered identity as a renunciant bodhisattva, Pitkin illuminates Tibetan and Himalayan practices of memory, affective connection, and mourning. Refuting long-standing caricatures of Tibetan Buddhist communities as unable to be modern because of their religious commitments, Pitkin shows instead how twentieth- and twenty-first-century Tibetan and Himalayan Buddhist narrators have used themes of renunciation, devotion, and lineage as touchstones for negotiating loss and vitalizing continuity.

Book Description
This well-illustrated work is the first attempt to bridge the gap between several specialized discourses concerning Japanese theatre. Central are problems of scholarly and practical reception of Japanese theatre forms in the West. The essays by a careful selection of internationally well-reputed scholars range widely through Japanese theatre, from the ancient to the postmodern, or, one might say, from kagura to angura. It deals with reception of Japanese theatre in the West, the treatment of the body in stage art and drama, Western influence, the impact of Japanese theatre practice and theory upon the actor’s training, and stage directing in the West. Readers will come across a wide variety of intriguing topics, such as lion dances, kabuki, nôh, folk theatre, taishu engeki, and several important modern playwrights, etc. This book truly promises to intensify future dialogue between the many disciplines concerned with Japanese theatre.
