Abstract

Surveillance systems are widely used in defense environments to monitor activities and ensure security. However, images captured by surveillance cameras often suffer from low illumination, noise, blur, and poor contrast due to environmental conditions. These issues reduce the visibility of important objects and make analysis difficult. Therefore, improving the visual quality of surveillance images is essential for effective monitoring and security operations. This work proposes a Dynamic Visual Quality Enhancement (DVQE) system that enhances the visual quality of surveillance images using image processing techniques. The system processes images through several stages, including image acquisition, preprocessing, noise reduction, contrast enhancement, and brightness adjustment. Techniques such as filtering, histogram equalisation, and gamma correction are applied to improve image visibility and reveal hidden details. The enhanced images provide better clarity and improved structural information, making it easier to identify objects such as vehicles, people, and other important elements in surveillance footage. Experimental results show that the proposed method effectively improves brightness, contrast, and overall image quality, thereby supporting efficient monitoring and decision-making in defence surveillance environments.

Full Article/Conclusion

             The Dynamic Visual Quality Enhancement (DVQE) system for surveillance in defense environments effectively addresses the challenges posed by low-light, foggy, or noisy conditions. By integrating deep learning-based image enhancement techniques with real-time video processing, the system significantly improves the clarity, brightness, and contrast of surveillance footage.   Enhanced visual quality allows for more accurate object detection using models such as YOLO, enabling defense personnel to identify vehicles, humans, drones, or suspicious activities with greater reliability. The system also provides quantitative evaluation through metrics like PSNR and SSIM, ensuring that the structural integrity of images is preserved while reducing noise and distortion.   Overall, the DVQE framework offers an intelligent, automated solution for real-time surveillance monitoring, enhancing situational awareness, reducing response times, and supporting more informed decision-making in defense operations. Its modular design, combining acquisition, preprocessing, enhancement, quality assessment, and monitoring, makes it adaptable and scalable for various defense scenarios.
