Performance Improvement of Electro Optic Search and Track System for Maritime Surveillance

Abstract

Surveillance of maritime domain is absolutely vital to ensure an appropriate response against any adverse situation relating to maritime safety or security. Electro-optic search and track (EOST) system plays a vital role by providing independent search and track of potential targets in marine environment. EOST provides real-time images of objects with details, required to neutralise threats. At long range, detection and tracking capability of EOST degrades due to uncertainty in target signatures under cluttered scenario. Image quality can be improved by using suitable sensors and enhancement using the target/background signature knowledge. Robust tracking of object can be achieved by optimising the performance parameters of tracker. In the present work, improvement in the performance of EOST subsystems such as sensor, video processor and video tracker are discussed. To improve EOST performance in terms of detection and tracking, sensor selection criterion and various real time image processing techniques and their selection criteria for maritime applications have been also discussed. Resultant improvement in the quality of image recorded under marine environment has been presented.

Parallel Three-Branch Correlation Filters for Complex Marine Environmental Object Tracking Based on a Confidence Mechanism

“…Due to the complexity of the marine environment, it is meaningful to study the tracking of complex marine environmental objects [ 1 ]. Owing to changes in appearance, changes in lighting, fast motion, blur and partial occlusion, it is difficult for traditional visual object trackers to achieve accurate and robust tracking of complex marine environmental objects [ 2 ]. Therefore, based on the in-depth analysis of the visual object tracking technology, this passage proposes a series of strategies to improve the tracking performance for complex marine environmental objects.…”

Two Dimensional Materials for Military Applications

“…Besides, a variety of materials ranging from nano to macro scale are developed for sensor technologies such as detectors, and electronic card components like chips, microprocessors, and diodes 10,11 . Specifically, sensors provide the required data to evaluate or optimize the required decision making in military operations 12,13 . Moreover, advanced electronic devices such as processors or nano/microchips are essential to high-speed data and image processing, computing, and networking, especially to process and optimize big data.…”
