New York, 2101. Le jeune Jake est choisi pour devenir la plus grande star internationale. Ancien esclave, il découvre le monde des humains, leur technologie et FREESCOM, la puissante entreprise à laquelle il appartient désormais. Un entraînement intensif et une médiatisation à outrance le placent sur le devant de la scène. Il incarne alors un idéal suprême et garantit à ses supérieurs la consommation effrénée des masses. Mais qui est-il vraiment et que cache sa starisation ? Il ne tardera pas à rassembler les pièces du puzzle, à partir sur les traces de sa famille et à tenter de sauver son humanité. Miroir déformant des années 90 où l'Amérique est la grande puissance et la télévision le vecteur principal d'uniformisation, ce roman d'anticipation sociale dénonce le conditionnement des individus et la standardisation. Dans ce monde-là, politique, médias et divertissement ne font qu'un, servant des intérêts privés. Les stars et leur sex-appeal ont installé une nouvelle religion: la tyrannie de la séduction.

This book focuses on the super resolution of images and video. The authors' use of the term super resolution (SR) is used to describe the process of obtaining a high resolution (HR) image, or a sequence of HR images, from a set of low resolution (LR) observations. This process has also been referred to in the literature as resolution enhancement (RE). SR has been applied primarily to spatial and temporal RE, but also to hyperspectral image enhancement. This book concentrates on motion based spatial RE, although the authors also describe motion free and hyperspectral image SR problems. Also examined is the very recent research area of SR for compression, which consists of the intentional downsampling, during pre-processing, of a video sequence to be compressed and the application of SR techniques, during post-processing, on the compressed sequence. It is clear that there is a strong interplay between the tools and techniques developed for SR and a number of other inverse problems encountered in signal processing (e.g., image restoration, motion estimation). SR techniques are being applied to a variety of fields, such as obtaining improved still images from video sequences (video printing), high definition television, high performance color Liquid Crystal Display (LCD) screens, improvement of the quality of color images taken by one CCD, video surveillance, remote sensing, and medical imaging. The authors believe that the SR/RE area has matured enough to develop a body of knowledge that can now start to provide useful and practical solutions to challenging real problems and that SR techniques can be an integral part of an image and video codec and can drive the development of new coder-decoders (codecs) and standards.
