"An exploration of depictions and use of water within Renaissance Italy, and especially in the work of polymath Leonardo da Vinci. Both a practical necessity and a powerful symbol, water presents one of the most challenging problems in visual art due to its formlessness, clarity, and mutability. In Renaissance Italy, it was a nearly inexhaustible subject of inquiry for artists, engineers, and architects alike: it represented an element to be productively harnessed and a force of untamed nature. Watermarks places the depiction and use of water within an intellectual history of early modern Italy, examining the parallel technological and aesthetic challenges of mastering water and the scientific and artistic practices that emerged in response to them. Focusing primarily on the wide-ranging work of Leonardo da Vinci (1452-1519)-at once an artist, scientist, and inventor-Leslie Geddes shows how the deployment of artistic media, such as ink and watercolor, closely correlated with the engineering challenges of controlling water in the natural world. For da Vinci and his peers, she argues, drawing was an essential form of visual thinking. Geddes analyses a wide range of da Vinci's subject matter, including machine drawings, water management schemes, and depictions of the natural landscape, and demonstrates how drawing-as an intellectual practice, a form of scientific investigation, and a visual representation-constituted a distinct mode of problem solving integral to his understanding of the natural environment. Throughout, Geddes draws important connections between works by da Vinci that have long been overlooked, the artistic and engineering practices of his day, and critical questions about the nature of seeing and depicting the almost unseeable during the early modern period"--

Watermarking techniques involve the concealment of information withina text or images and the transmission of this information to thereceiver with minimum distortion. This is a very new area ofresearch. The techniques will have a significant effect on defence, business, copyright protection and other fields where informationneeds to be protected at all costs from attackers.This book presents the recent advances in the theory andimplementation of watermarking techniques. It brings together, for thefirst time, the successful applications of intelligent paradigms(including comparisons with conventional methods) in many areas. Theaccompanying CD-Rom provides readers with source codes and executablesto put into practice general topics in watermarking

From Christy Ann Conlin, the critically acclaimed and award winning author of Heave, comes a breathtaking and unforgettable collection about how the briefest moment can shape us forever. In these evocative and startling stories, we meet people navigating the elemental forces of love, life, and death. An insomniac on Halifax’s moonlit streets. A runaway bride. A young woman accused of a brutal murder. A man who must live in exile if he is to live at all. A woman coming to terms with her eccentric childhood in a cult on the Bay of Fundy shore. A master of North Atlantic Gothic, Christy Ann Conlin expertly navigates our conflicting self-perceptions, especially in moments of crisis. She illuminates the personality of land and ocean, charts the pull of the past on the present, and reveals the wildness inside each of us. These stories offer a gallery of both gritty and lyrical portraits, each unmasking the myth and mystery of the everyday.

Machine learning (ML) models, especially large pretrained deep learning (DL) models, are of high economic value and must be properly protected with regard to intellectual property rights (IPR). Model watermarking methods are proposed to embed watermarks into the target model, so that, in the event it is stolen, the model’s owner can extract the pre-defined watermarks to assert ownership. Model watermarking methods adopt frequently used techniques like backdoor training, multi-task learning, decision boundary analysis etc. to generate secret conditions that constitute model watermarks or fingerprints only known to model owners. These methods have little or no effect on model performance, which makes them applicable to a wide variety of contexts. In terms of robustness, embedded watermarks must be robustly detectable against varying adversarial attacks that attempt to remove the watermarks. The efficacy of model watermarking methods is showcased in diverse applications including image classification, image generation, image captions, natural language processing and reinforcement learning. This book covers the motivations, fundamentals, techniques and protocols for protecting ML models using watermarking. Furthermore, it showcases cutting-edge work in e.g. model watermarking, signature and passport embedding and their use cases in distributed federated learning settings.

Digital audio, video, images, and documents are flying through cyberspace to their respective owners. Unfortunately, along the way, individuals may choose to intervene and take this content for themselves. Digital watermarking and steganography technology greatly reduces the instances of this by limiting or eliminating the ability of third parties to decipher the content that he has taken. The many techiniques of digital watermarking (embedding a code) and steganography (hiding information) continue to evolve as applications that necessitate them do the same. The authors of this second edition provide an update on the framework for applying these techniques that they provided researchers and professionals in the first well-received edition. Steganography and steganalysis (the art of detecting hidden information) have been added to a robust treatment of digital watermarking, as many in each field research and deal with the other. New material includes watermarking with side information, QIM, and dirty-paper codes. The revision and inclusion of new material by these influential authors has created a must-own book for anyone in this profession. This new edition now contains essential information on steganalysis and steganography New concepts and new applications including QIM introduced Digital watermark embedding is given a complete update with new processes and applications
