Auto-video Tracking System: Performance Evaluation

Automatic target tracking systems are employed in a wide variety of missions and tracking environment such as fire control, guidance, navigation, passive range estimation, and automatic target discrimination. The tracker performance depends upon target size, contrast, speed, and signal-to-noise ratio. The evaluation of a tracker system involves lengthy field trials and measurements. In the present article, a method for quick evaluation of tracker system and working out selection criteria for different tracking algorithm for various target and background combinations have been suggested. Performance measures such as aiming point error, duration of successful tracking, number of tracking losses, indication of confidence, and system reaction time have been used to evaluate the performance of a tracking system.
