This paper intends to study whether thermal and visible image fusion improves ear recognition given illumination variations. Five fusion methods, namely, simple average, mean average, average discrete wavelet transform (DWT), optimized DWT and weighted DWT were tested. The experiments were done using DIAST Variability Illuminated Thermal and Visible Ear Image Datasets. There were two experiments conducted...
As the research in ear biometrics grows, there is a need to have a publicly available ear images database for researchers to test and validate their methods. There are many available ear databases captured in visible light domain. However, images in those databases are mostly acquired in a controlled environment, not in naturally illuminated environments. Up to the point of writing, there is no thermalbased...
This paper describes the use of Otsu thresholding method in assessing the radiation pattern emitted by near infrared (NIR) LED. The NIR LED configured in this paper is intended to be used as illumination source for the development of a NIR palm vein image acquisition device. The experiment is conducted using a single board computer (SBC) to promote a real-time embedded system development that can...
Energy can be reused or saved instead of simply wasted by implementing strategic planning. In commercial building, energy consumption varies due to various factors such as building design, climate, load usage, type of electrical appliances, and management. Since each room in a building is designed to accommodate certain number of occupant, the room capacity is also considered as one of the factors...
Energy Efficiency is one of the main focuses of research in Electrical Engineering at the present time. Lighting system carries a considerable amount of the total electricity usage in buildings. Hence researchers have been continuously thriving to achieve better efficiency in lighting, which means maintaining optimum lighting conditions using as less energy as possible. Using energy efficient lamps...
