Mathematical Techniques In Multisensor Data Fusion 2nd Ed.

by David Hall, Sonya A. H. McMullen, Sonya A. H. McMullen (Joint Author)

Overview

Since the publication of the first edition of this book, advances in algorithms, logic and software tools have transformed the field of data fusion. The latest edition covers these areas as well as smart agents, human computer interaction, cognitive aides to analysis and data system fusion control. data fusion system, this book guides you through the process of determining the trade-offs among competing data fusion algorithms, selecting commercial off-the-shelf (COTS) tools, and understanding when data fusion improves systems processing. Completely new chapters in this second edition explain data fusion system control, DARPA's recently developed TRIP model, and the latest applications of data fusion in data warehousing and medical equipment, as well as defence systems.

Editorial Reviews

Research into how to combine data from multiple (and sometimes different) sensors to find out what is going on, has been split between military (battlefield surveillance, etc.) and non-military (robotics, etc.) concerns. The two groups don't speak to each other, and have developed different approaches, techniques, and terminology. Here is a distillation of the mathematics they both use for data- fusion reduced to the bare bones to be comprehensible to researchers and application engineers in many fields. Annotation c.
