Today, more than 80% of the data transmitted over networks and archived on our computers, tablets, cell phones or clouds is multimedia data - images, videos, audio, 3D data. The applications of this data range from video games to healthcare, and include computer-aided design, video surveillance and biometrics.It is becoming increasingly urgent to secure this data, not only during transmission and archiving, but also during its retrieval and use. Indeed, in today's'all-digital'world, it is becoming ever-easier to copy data, view it unrightfully, steal it or falsify it.Multimedia Security 1 analyzes the issues of the authentication of multimedia data, code and the embedding of hidden data, both from the point of view of defense and attack. Regarding the embedding of hidden data, it also covers invisibility, color, tracing and 3D data, as well as the detection of hidden messages in an image by steganalysis.

Point clouds from LiDAR and photogrammetry are vital and vast sources of geospatial information besides remote sensing imagery. This book provides the latest theory and methodology for point cloud processing with AI to better serve earth observation, 3D vision, autonomous driving, smart city, and geospatial information applications. It covers various aspects of 3D geospatial information, including data capturing, fusing, geocomputing, modeling, and vast downstream applications. With the inclusion of numerous illustrations, diagrams, and practical applications, readers will better understand the point cloud, and its technical challenges, and learn how to utilize point cloud in different fields.Features Provides in-depth point cloud processing pipeline, cutting-edge theory, and technology with AI. Includes many specific applications of point cloud in the geospatial field. Offers a comprehensive step-by-step guide from theory to application in point cloud processing. Includes ample supplementary materials including datasets, tools, and other online resources. Helps readers across many disciplines, from geospatial to engineering, to understand the vast application of point clouds and how to further generate new ideas and innovative thoughts. This book is an excellent resource for researchers, academics, students, and professionals in a variety of fields including Geomatics, Remote Sensing, Cartography and Geographic Information Systems, Data Science, Geography, Earth Science, and more.

This Singaporean-French Symposium aims to strengthen existing research collaboration between French and Singapore scientists, and to explore and develop new collaborations in IPAL (Image Perception, Access & Language) — the Singaporean-French international research lab created between the French National Research Center (CNRS), the National University of Singapore (NUS), the Institute for Infocomm Research (I2 R-A∗STAR) and the Joseph Fourier University (UJF). SinFra'09 welcomes researchers and collaborators under IPAL organizations and those who wish to collaborate with IPAL. The symposium proposes Tutorials and Scientific Sessions in relevant Singaporean — French common interest fields, related to the present and possible future activities in IPAL. We seek submissions of high-quality, original work in the following areas: existing IPAL areas like Medical Image Analysis and Access, Mobile Information Access, and also new areas of collaboration between French and Singaporean scientists, such as interactive digital media, cognitive vision and audio, video surveillance and security, real-time / embedded systems, media and sensors networks, programming languages, language-based security and quantum informatics.
