"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

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.

Multimedia Encryption and Watermarking presents a comprehensive survey of contemporary multimedia encryption and watermarking techniques, which enable a secure exchange of multimedia intellectual property. Part I, Digital Rights Management (DRM) for Multimedia, introduces DRM concepts and models for multimedia content protection, and presents the key players. Part II, Multimedia Cryptography, provides an overview of modern cryptography, with the focus on modern image, video, speech, and audio encryption techniques. This book also provides an advanced concept of visual and audio sharing techniques. Part III, Digital Watermarking, introduces the concept of watermarking for multimedia, classifies watermarking applications, and evaluates various multimedia watermarking concepts and techniques, including digital watermarking techniques for binary images. Multimedia Encryption and Watermarking is designed for researchers and practitioners, as well as scientists and engineers who design and develop systems for the protection of digital multimedia content. This volume is also suitable as a textbook for graduate courses on multimedia security.
