The Message Of Images

New multimedia database search tools require rapidity, compression, image quality and copyright control. The two latter are often covered by embedding a hidden watermark signal in the multimedia content. More effective and recognized multimedia search methods are using hash functions. Hash functions compute very short signatures characteristically very different from one media to another. Typical requirement of hash functions are: easily computable, provide short output bit length, and collision resistant. In this thesis, an image hashing method for multimedia contents is presented as an innovative solution for content identification and indexing. This new one-way function for images extract some image features by different computations along radial projections. The magnitude of change is related to the amount of the change of the media (image, video). In watermarking, hashing enables the creation of payloads that depend on the media content, and which are thus resistant to the "copy attack" and collusion. This thesis is available in the SIMILAR collection under the label « Presses universitaires de Louvain » (ISBN 2-930344-58-X) and may be purchased online at www.i6doc.com.

Why do we have such extraordinarily powerful responses toward the images and pictures we see in everyday life? Why do we behave as if pictures were alive, possessing the power to influence us, to demand things from us, to persuade us, seduce us, or even lead us astray? According to W. J. T. Mitchell, we need to reckon with images not just as inert objects that convey meaning but as animated beings with desires, needs, appetites, demands, and drives of their own. What Do Pictures Want? explores this idea and highlights Mitchell's innovative and profoundly influential thinking on picture theory and the lives and loves of images. Ranging across the visual arts, literature, and mass media, Mitchell applies characteristically brilliant and wry analyses to Byzantine icons and cyberpunk films, racial stereotypes and public monuments, ancient idols and modern clones, offensive images and found objects, American photography and aboriginal painting. Opening new vistas in iconology and the emergent field of visual culture, he also considers the importance of Dolly the Sheep—who, as a clone, fulfills the ancient dream of creating a living image—and the destruction of the World Trade Center on 9/11, which, among other things, signifies a new and virulent form of iconoclasm. What Do Pictures Want? offers an immensely rich and suggestive account of the interplay between the visible and the readable. A work by one of our leading theorists of visual representation, it will be a touchstone for art historians, literary critics, anthropologists, and philosophers alike. “A treasury of episodes—generally overlooked by art history and visual studies—that turn on images that ‘walk by themselves’ and exert their own power over the living.”—Norman Bryson, Artforum

Mass Moralizing: Marketing and Moral Storytelling examines the narratives of today’s brand marketing, which largely focuses on creating an emotional attachment to a brand rather than directly promoting a product’s qualities or features. Phil Hopkins explores these narratives’ influence on how we think about ourselves and our moral possibilities, our cultural ideas about morality, and our relations to each other. He closely studies the relationship between three interrelated dynamics: the power of narrative in the construction of identity and world, the truth-telling pretenses of mass marketing, and the growth of moralizing as the primary moral discourse practice in contemporary consumer culture. Mass Moralizing scrutinizes the way marketing speaks to us in explicitly moralistic terms, significantly influencing how we think about ourselves and our moral possibilities.
