Moving target detection and tracking with camera in real-time is a hot field of research in the current era. Due to the advancement in computer, it is need of the day to make machine's perception, vision and intelligence like humans. The goal of this book is to present a research and real-time implementation of moving target detection, tracking and locking system. Many algorithms are reviewed and the latest and efficient ones are implemented. Hope that this work will help many researches who want to do research in the field of detection and tracking in real-time scenarios.
