Real-time histograms for tracking systems: data acquisition data presentation and user interfaces

摘要

Implementation of a target acquisition tracker on real time video images can be made to run with more modest processors by using intensity thresholds. Pixels are ignored in real- time based on this threshold setting, hence reducing processor time. This paper considers issues when a real-time histogram is presented to a user and how the decision can be made rapidly by a user. This paper also describes a common tracking algorithm adapted to using this threshold, and a hybrid mode. The paper will also show how a system's user interface is designed to rapidly gather this information without overloading the user.
