Fuzzy Based Night Color Image Enhancement
Abstract: This paper presents an algorithm based on fuzzy sets for enhancement of images captured during night. HSV color space is employed to extract S and V components of the image and fuzzification is carried out on the V component. The fuzzified membership function is modified, defuzzified and three iterations are carried out. This algorithm enhances the dark region by restraining the glaring region, adjusting the contrast, distributing luminance evenly and …

Design of Electrostatic RF Switch using COMSOL
Abstract: This paper presents the design, modeling, and measurements of radio frequency micro electromechanical systems (RF MEMS) switches. These models are rectangular, taper, and meandering beam structures. The characteristics of RF MEMS switches including displacement and natural frequency are studied. Rectangular, taper, and meandering structures are selected because these three structures display different geometrical shapes. Geometrical shapes are one of the important factors as far as the mechanical and electronic characteristics …

Biomedical Image Processing: Retinal Blood Vessel Segmentation using Graph Cut Technique
Abstract: Retinal image, which is used in determining different diseases in the eye of a human being, is an important feature in the field of ophthalmology. Similarly, optic disc detection is also an important feature as it locates diseases and defects. In Image processing of fundus, image vessel extraction is the key feature used in doing so. Here, we are presenting the Graph Cut method which helps in extracting blood vessels …

Role of Biosensors and Image Processing for Improving Quality Inspection of Food Products: A Review
Abstract: Every year, millions of people experience serious and sometimes fatal health problems due to consumption of unsafe or contaminated food. Biosensors and image processing techniques provide solutions to some of the challenges that arise in food inspection. The conventional food-inspection techniques which depend on collection of samples followed by qualitative analysis in labs are time-consuming and inspections are not too much efficient. With the advancement of technology in computers, scientific …

Hand Geometry based Person Identification System using Support Vector Machine
Abstract: In recent times, it is immensely important to identify a person to access the secure data in a system. In this case, verification and identification techniques play a vital role to secure the process. Password system has failed to provide such kind of security. We highly emphasize on the biometric characteristics to design such secured systems. In this paper, we provide a way to identify a unique person by his …

Study of Real-Time System for Monitoring and Analyzing ECG Using Cell Phone: A Review
Abstract: Health conditions of various patients suffering from cardiac diseases need to be monitored time to time. This is due to the criticality of these conditions which are mainly related to cardiac dis orders. Thus patients need to be followed up on a regular basis. An immediate follow-up can be facilitated in a real environment. A portable device can act suitably as a real environment here in such conditions. A hand-held …
