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(More)
Accurate detection of depression at an individual level using structural magnetic resonance imaging (sMRI) remains a challenge. Brain volumetric changes at a structural level appear to have importance in depression biomarkers studies. An automated algorithm is developed to select brain sMRI volumetric features for the detection of depression. A feature(More)
Depression is a major issue worldwide and is seen as a significant health problem. Stigma and patient denial, clinical experience, time limitations, and reliability of psychometrics are barriers to the clinical diagnoses of depression. Thus, the establishment of an automated system that could detect such abnormalities would assist medical experts in their(More)
Mobile phones produce radio frequency signal that is transferred as Electromagnetic radiation (EMR). EMR has the ability to penetrate through semi solid substances especially human body's tissues and caused dielectric heating. This effect can be classified as thermal and non thermal radiation. The skin near ear skull region is very thin compare to other(More)
Brain volume changes at structural level appear to have utmost importance in depression biomarkers studies. However, these brain volumetric findings have very minimal utilization in depression detection studies at individual level. Thus, this paper presents an evaluation of volumetric features to identify the relevant/optimal features for the detection of(More)
In recent years, the public concern on human biological effect of mobile phone is increasing due to the widely used of mobile phones by public including the children. As a consequences, a safety guidelines have been established by the various public organization such as World Health Organization (WHO) and International Commission on Non-Ionization Radiation(More)
Studies show that exposure to the electromagnetic wave for a certain period of time will leads to health problem such as headaches, or even worse, brain cancer. Scientist have known that this radiation might cause human biological damage through heating effects since human body is made up of approximately 65–70% water, electrolytes and ions. Radio(More)
To be diagnostically effective, structural magnetic resonance imaging (sMRI) must reliably distinguish a depressed person from a healthy one at individual scan level. One of the tasks in the automated diagnosis of depression from brain sMRI is the classification of samples (i.e., depressed/not depressed, remitted/not-remitted depression) based on the values(More)
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(More)
