Tracking Humans from the Author: David Diaz. Tracker. The very word evokes images of buckskin-clad braves crouching over the ground, carefully studying the signs before them—a part of history. But the modern world has not put behind it the need for the earthy business of tracking. Such skills are still routinely used by the military, rescue personnel, and law enforcement, as well as by hunters and people living at subsistence level throughout the world. Tracking Humans is the ultimate authoritative guide to this most complex pursuit. A great resource for military, law enforcement, and rescue professionals, Tracking Humans is also useful for outdoor enthusiasts. Users will find it invaluable as an on-site manual to assist in any ongoing search. Unlike many tracking manuals, this guide focuses on tracking humans, whether they're enemy combatants or lost children. Author David Diaz explains what it takes to be an expert tracker, from the physical stamina to the focus and perception necessary to do the job correctly. He explains the tools of the tracker and presents essential safety tips every tracker should know. Tracking Humans is an important tool for anyone dealing with missing persons—it could be an essential lifesaver.

Conditional Random People Tracking Humans With Crfs And Grid Filters from the Author: . We describe a state-space tracking approach based on a Conditional Random Field (CRF) model, where the observation potentials are learned from data. We find functions that embed both state and observation into a space where similarity corresponds to L1 distance, and define an observation potential based on distance in this space. This potential is extremely fast to compute and in conjunction with a grid-filtering framework can be used to reduce a continuous state estimation problem to a discrete one. We show how a state temporal prior in the grid-filter can be computed in a manner similar to a sparse HMM, resulting in real-time system performance. The resulting system is used for human pose tracking in video sequences.

Analyzing Video Sequences Of Multiple Humans from the Author: Jun Ohya. Analyzing Video Sequences of Multiple Humans: Tracking, Posture Estimation and Behavior Recognition describes some computer vision-based methods that analyze video sequences of humans. More specifically, methods for tracking multiple humans in a scene, estimating postures of a human body in 3D in real-time, and recognizing a person's behavior (gestures or activities) are discussed. For the tracking algorithm, the authors developed a non-synchronous method that tracks multiple persons by exploiting a Kalman filter that is applied to multiple video sequences. For estimating postures, an algorithm is presented that locates the significant points which determine postures of a human body, in 3D in real-time. Human activities are recognized from a video sequence by the HMM (Hidden Markov Models)-based method that the authors pioneered. The effectiveness of the three methods is shown by experimental results.

Computational Studies Of Human Motion from the Author: David A. Forsyth. Computational Studies of Human Motion: Part 1, Tracking and Motion Synthesis reviews methods for kinematic tracking of the human body in video. The review confines itself to the earlier stages of motion, focusing on tracking and motion synthesis. There is an extensive discussion of open issues. The authors identify some puzzling phenomena associated with the choice of human motion representation --- joint angles vs. joint positions. The review concludes with a quick guide to resources and an extensive bibliography of over 400 references. Computational Studies of Human Motion: Part 1, Tracking and Motion Synthesis is an invaluable reference for those engaged in computational geometry, computer graphics, image processing, imaging in general, and robotic.

Multimodal Technologies For Perception Of Humans from the Author: Rainer Stiefelhagen. This book constitutes the thoroughly refereed post-proceedings of the First International CLEAR 2006 Evaluation Campaign and Workshop on Classification of Events, Activities and Relationships for evaluation of multimodal technologies for the perception of humans, their activities and interactions. The workshop was held in the UK in April 2006. The papers were carefully reviewed and selected for inclusion in the book.

Control Theory For Humans from the Author: Richard J. Jagacinski. This textbook provides a tutorial introduction to behavioral applications of control theory. Control theory describes the information one should be sensitive to and the pattern of influence that one should exert on a dynamic system in order to achieve a goal. As such, it is applicable to various forms of dynamic behavior. The book primarily deals with manual control (e.g., moving the cursor on a computer screen, lifting an object, hitting a ball, driving a car), both as a substantive area of study and as a useful perspective for approaching control theory. It is the experience of the authors that by imagining themselves as part of a manual control system, students are better able to learn numerous concepts in this field. Topics include varieties of control theory, such as classical, optimal, fuzzy, adaptive, and learning control, as well as perception and decision making in dynamic contexts. The authors also discuss implications of control theory for how experiments can be conducted in the behavioral sciences. In each of these areas they have provided brief essays intended to convey key concepts that enable the reader to more easily pursue additional readings. Behavioral scientists teaching control courses will be very interested in this book.

Canine Tracking Guide from the Author: Don Abney. Canine Tracking Guide details the two most common uses of the canine nose: following blood trails for wounded game and tracking humans (from lost children and missing hikers, to escaped convicts). The author explains the concept of human scent and how the amazing canine nose functions and then elaborates on the basic training principles, commands, exercises and patterns used in tracking work. Whether a reader is working with hunting dogs, police dogs, cadaver dogs or competition dog, this guide offers the correct information needed for every tracking pursuit.

Building The Information Society from the Author: Rene Jacquart. In the context of the 18th IFIP World Computer Congress (WCC’04), and beside the traditional organization of conferences, workshops, tutorials and student forum, it was decided to identify a range of topics of dramatic interest for the building of the Information Society. This has been featured as the "Topical day/session" track of the WCC’04. Topical Sessions have been selected in order to present syntheses, latest developments and/or challenges in different business and technical areas. Building the Information Society provides a deep perspective on domains including: the semantic integration of heterogeneous data, virtual realities and new entertainment, fault tolerance for trustworthy and dependable information infrastructures, abstract interpretation (and its use for verification of program properties), multimodal interaction, computer aided inventing, emerging tools and techniques for avionics certification, bio-, nano-, and information technologies, E-learning, perspectives on ambient intelligence, the grand challenge of building a theory of the Railway domain, open source software in dependable systems, interdependencies of critical infrastructure, social robots, as a challenge for machine intelligence. Building the Information Society comprises the articles produced in support of the Topical Sessions during the IFIP 18th World Computer Congress, which was held in August 2004 in Toulouse, France, and sponsored by the International Federation for Information Processing (IFIP).
