Real-Time Progressive Hyperspectral Image Processing
by Chein-I ChangThe book covers the most crucial parts of real-time hyperspectral image processing: causality and real-time capability. Recently, two new concepts of real time hyperspectral image processing, Progressive HyperSpectral Imaging (PHSI) and Recursive HyperSpectral Imaging (RHSI). Both of these can be used to design algorithms and also form an integral part of real time hyperpsectral image processing. This book focuses on progressive nature in algorithms on their real-time and causal processing implementation in two major applications, endmember finding and anomaly detection, both of which are fundamental tasks in hyperspectral imaging but generally not encountered in multispectral imaging. This book is written to particularly address PHSI in real time processing, while a book, Recursive Hyperspectral Sample and Band Processing: Algorithm Architecture and Implementation (Springer 2016) can be considered as its companion book.
Real-Time Recursive Hyperspectral Sample and Band Processing
by Chein-I ChangThis book explores recursive architectures in designing progressive hyperspectral imaging algorithms. In particular, it makes progressive imaging algorithms recursive by introducing the concept of Kalman filtering in algorithm design so that hyperspectral imagery can be processed not only progressively sample by sample or band by band but also recursively via recursive equations. This book can be considered a companion book of author's books, Real-Time Progressive Hyperspectral Image Processing, published by Springer in 2016.
Real-Time Rendering: Computer Graphics with Control Engineering (Automation and Control Engineering #49)
by Gabriyel Wong Jianliang WangConsumers today expect extremely realistic imagery generated in real time for interactive applications such as computer games, virtual prototyping, and scientific visualisation. However, the increasing demands for fidelity coupled with rapid advances in hardware architecture pose a challenge: how do you find optimal, sustainable solutions to accommodate both speed of rendering and quality? Real-Time Rendering: Computer Graphics with Control Engineering presents a novel framework for solving the perennial challenge of resource allocation and the trade-off between quality and speed in interactive computer graphics rendering. Conventional approaches are mainly based on heuristics and algorithms, are largely application specific, and offer fluctuating performance, particularly as applications become more complex. The solution proposed by the authors draws on powerful concepts from control engineering to address these shortcomings. Expanding the horizon of real-time rendering techniques, this book: Explains how control systems work with real-time computer graphics Proposes a data-driven modelling approach that more accurately represents the system behaviour of the rendering process Develops a control system strategy for linear and non-linear models using proportional, integral, derivative (PID) and fuzzy control techniques Uses real-world data from rendering applications in proof-of-concept experiments Compares the proposed solution to existing techniques Provides practical details on implementation, including references to tools and source code This pioneering work takes a major step forward by applying control theory in the context of a computer graphics system. Promoting cross-disciplinary research, it offers guidance for anyone who wants to develop more advanced solutions for real-time computer graphics rendering.

Real-time Security Extensions for EPCglobal Networks: Case Study for the Pharmaceutical Industry
by Matthieu-P. SchapranowThe transformation towards EPCglobal networks requires technical equipment for capturing event data and IT systems to store and exchange them with supply chain participants. For the very first time, supply chain participants thus need to face the automatic exchange of event data with business partners. Data protection of sensitive business secrets is therefore the major aspect that needs to be clarified before companies will start to adopt EPCglobal networks. This book contributes to this proposition as follows: it defines the design of transparent real-time security extensions for EPCglobal networks based on in-memory technology. For that, it defines authentication protocols for devices with low computational resources, such as passive RFID tags, and evaluates their applicability. Furthermore, it outlines all steps for implementing history-based access control for EPCglobal software components, which enables a continuous control of access based on the real-time analysis of the complete query history and a fine-grained filtering of event data. The applicability of these innovative data protection mechanisms is underlined by their exemplary integration in the FOSSTRAK architecture.

Real Time Visual Effects for the Technical Artist
by Chris RodaVisual effects (VFX) are one of the most complicated components of feature film and television creation. With advancements in such technologies as Ray Tracing and Virtual Reality, the visual quality of the real-time rendering engine is now rivaling feature film. Real-time rendering requires years of programming experience with advanced understanding in math and physics. As the power of the real-time rendering engine improves, so too do the interfaces for VFX creation. With limited technical understanding, artists can create VFX with the push of a button and tug of a slider. As powerful as the interfaces are, they can only expose a portion of the true potential of the rendering engine. Artists are limited by their understanding of the engine interface. Real Time Visual Effects for the Technical Artist is written for digital artists to explain the core concepts of VFX, common in all engines, to free them from interface bounds. Features: Introduces the reader to the technical aspects of real-time VFX Built upon a career of more than 20 years in the feature film VFX and the real-time video game industries and tested on graduate and undergraduate students Explores all real-time VFX in four categories: in-camera effects, in-material effects, simulations, and particles This book is written to complement undergraduate- or graduate-level courses focused on the fundamentals of modern real-time VFX. Chris Roda is a Technical Art instructor at the Florida Interactive Entertainment Academy (FIEA), a graduate degree program in interactive, real-time application development at the University of Central Florida. Early in his career, Chris was a visual effects artist in the film and television industries where he contributed visual effects for films such as Spider-Man, Titanic, and The Fifth Element. Before coming to FIEA, Chris was a CG Supervisor at Electronic Arts, where he worked on video game titles such as NCAA Football and Madden NFL Football. In addition to teaching, Chris works on generating tools and pipelines for the creation of immersive experiences: the amalgamation of the narrative of films, the interactivity of video games, and the immersion of theme parks.
