This paper mainly aims to study the performance of objective assessment methods of image quality. It take into consideration the correlations between each objective assessment and the subjective assessment in order to determine objective test performance. Three objective assessment methods used in this study are the Structural Similarity (SSIM) index, the Peak Signal-to-Noise Ratio (PSNR) and the...
There has been a large volume of research invested over the last decade into overcoming the difficulties inherent with propagation of information bearing signals through the underwater acoustic communications. This has been driven by an increasing demand for reliable and high capacity Underwater Acoustic Networks (UANs). Applications of interest in this area include oceanographic information gathering,...
Untraceable theft equipment is one of the problems faced by university campus. Some of these stolen equipments are untraceable due to their small size and portability. Lack of real-time notification and tracking ability of the stolen equipment prevents prompt and effective actions to be taken. Therefore, an system needs to be deployed within the campus that makes it possible to track down equipments...
Optical couplers are important device in optical communication networks to perform coupling functionalities. Gathering several signals in one optical communication network is not the significant problem now due to the emergence of various inventions of optical couplers. Users can choose the best coupling technique to fulfill their requirement. Resonant coupler based on Mach-Zehnder configuration can...
