This text describes some computer vision based methods that analyze methods for tracking multiple humans in a scene, estimating postures of a human body in 3D in real-time, and recognizing a person's gestures or activities. The five chapters detail the tracking algorithm developed by Ohya (Waseda U.), Utsumi (Advanced Telecommunications Research Institute) and Yamato (Nippon Telegraph and Telephone Corporation), which involves a non-synchronous method that exploits a Kalman filter applied to multiple video sequences. They also present the algorithm for estimating postures, and the method for recognizing human activities from a video sequence by the Hidden Markov Models. Appropriate for professional and academic researchers, as well as for use in graduate classes in computer vision or image processing. Annotation c. Book News, Inc., Portland, OR (booknews.com)
This book is an excellent reference for both professional and academic researchers in the fields of computer vision and image processing. It will also be of interest to those working in video surveillance and monitoring, virtual reality, computer graphics, pattern recognition, telecommunication, human-computer interface, and general computer science.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.The posture estimation method described in this book is a world-leading method in that it can estimate postures in 3D in real-time. As described in this book, the posture estimation method can be applied to avatar-based telecommunication systems, which require realistic, real-time reproduction of human images.This book is also suitable for use in graduate classes in computer vision or image processing.
