Abstract

Image processing techniques is been applied to process of imaging to obtain a more suitable output image for certain specific applications. Image processing improves the interpretability of an image for a human viewer. Visible quality of an image is enhanced by varying brightness, contrast, & histogram equalization. The analysis of image from tissues is very important for the detection of abnormalities. The images from abnormal regions are processed for distinguishing normal and abnormal regions. Commonly used method for analysis of medical images are based on software algorithm and the image enhancement algorithm with field programmable gate arrays (FPGA) implemented in hardware is a high performance. The image processing uses MATLABsimulator for processing. The proposed system of fundus image for detecting fluid filled abnormal regions of retina. The performance of the proposed system is evaluated¹.

Keywords

Abstract

A light activated switch for persons to operate switch-controlled computer software or other communication device has been developed. A light emitting diode is attached to the user’s forehead. An array of photo transistors is mounted at a fixed position from the body. It requires a small but controllable motion to activate the switch by aiming the LED beam at the target area of the receiver. The false activation due to uncontrollable motion will be a problem associated with cerebral palsy. The LED in the transmitter is driven by oscillator at 1 kHz and the band pass filter which is in receiver is tuned at that frequency¹. The level of received is detected by an amplitude demodulator once the signal is filtered. When the signals amplitude reach’s the threshold, a one short timer is triggered which then latches the switch for predetermined period. The system was tested by an 8 year old child and has demonstrated a satisfactory result. The sensivity and specificity are important factors for reliable operation of the light activated switch associated with the cerebral palsy.⁶

Abstract

Sleepiness either by Drowsy or Alcoholic is the main cursory factor for road accident and daytime malfunction. Especially, distinguishing driver’s laziness could capture drivers from impacts brought about by lazy driving. This paper point is to permit the dependable sign for identifying driver frumpiness dependent on the infrared sensors. In this paper we connected IR sensors which measure the beats every minutes (BPM) inconstancy of the driver which indicates tiredness of the subject. The target of this task is to plan and advancement of inbuilt IR sensor inside directing wheel of the vehicles. This laziness discovery framework is savvy and increasingly precise to lessen the episode of street mishap.
