چکیده

This paper describes a technique for extracting moving targets and robustly tracking them from real time video sequence. It consists of two phases: Initial segmentation, temporal tracking and optimal paraimeter selection. After target detection subsequent tracking is based on a modified Canny edge detection and accelerated Hausdorff measure. The modified canny edge detection algorithm produces closed loop edges. The manual optimization of the thresholds for edge detection is replaced by adaptive inputs based on the initial segmentation. An accelerated Hausdorff measure is used here to make the system computationally inexpensive. This technique differs from other methods in the following features: 1) Non-feature based method, 2) Can effectively track fast moving targets, 3) Modified Canny dege detection and accelerated Hausdorff measure for robust yet computationally inexpensive tracking, 5) dynamic template updation makes it sutable to track any unknown object. The resulting system robustly identifies targets of interest, rejects background clutter, and continually tracks over large distances despite occlusions, appearance changes, and cessation of target motion.

Effect of Curved Path Monopulse Radar Platform’s Grazing Angle on Height of Floated Targets Detection

Monopulse radarsare one of the most accurate tracking radars used to guide various platforms. Detection and tracking of surface targets with these radars are performed in order to point strike targets. Sea clutter presents challenges for detecting floated targets and in addition to affecting detection height, it can cause errors in monopulse angle finding. In this paper, the airborne monopulse ...

Optimal Observer Path Planning For Bearings-Only Moving Targets Tracking Using Chebyshev Polynomials

In this paper, an optimization problem for the observer trajectory in the bearings-only surface moving target tracking (BOT) is studied. The BOT depends directly on the observability of the target's position in the target/observer geometry or the optimal observer maneuver. Therefore, the maximum lower band of the Fisher information matrix is opted as an independent criterion of the target estim...
