Message Digests For Photographic Images And Video Contents

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.

This book presents the SIMILAR European research consortium in the field, the work under way and the great challenges posed by the development of the future multimodal interfaces.

Handbook of Forensic Photography is the most-comprehensive, definitive reference for the use of photography in the capture and presentation of forensic evidence. The intent is to inform the reader about the most complete and up-to-date methods to capture and reproduce images that most accurately represent the evidence. With the rise in importance of forensic science, crime and accident scene documentation has likewise increased in importance—not the least of which has been forensic photography. The need to use accepted practice and protocols to guarantee the authenticity of images for evidence documentation is paramount for using it in court. And as with any discipline, there is an art to the science of forensic photography. Contributing authors from various backgrounds—each experts in their field—have provided numerous case examples, best practices, and recommendations for recognizing, recording, and preserving evidence using cameras and the latest digital image technology, including video and other imaging technologies. Chapters present such topics as videography, drone photography, underwater photography, crime scene photography, autopsy photographs, fire documentation, forensic odontology, and more. The book closes with coverage of courtroom displays, presenting imaging evidence and expert witness testimony in the courtroom. Handbook of Forensic Photography is a must-have reference for experienced crime scene photographers, death and crime scene investigators, police, and forensic professionals—including medical examiners, odontologists, engineers, and forensic anthropologists—who frequently need to capture investigative photographs in the course of investigations.

Experiencing Public Relations examines the everyday experiences of PR practitioners in order to better understand how public relations is perceived by those outside and within the field. The book aims to provoke debate around the nature of public relations by looking at how it is defined at a theoretical level, compared to how it is lived and represented in the real world. Chapters feature work from some of the world’s leading public relations scholars. They cover a diverse range of subjects, such as representations of PR in fiction and film, terrorist use of public relations, the impact of social media on this medium and a study of ‘dirty work’ within the PR industry. The book also explores international PR practices, presenting analysis from contributors based in Australia, Germany, India, Norway, New Zealand, Poland, Russia, Slovenia, Spain, South Africa, Sweden, Taiwan, UAE, UK, USA and Venezuela. Experiencing Public Relations goes beyond the ‘frontstage’ scholarship of public relations to bring together stories of PR in daily life, revealing how influential theories work out in practice and translate into different cultural and social contexts. This book will provide researchers, professionals and students with a vital perspective on the inner workings of public relations today.
