The next generation of broadband mobile communication system will face challenges caused by propagation characteristics of channel with much broader bandwidth as well as the need for a much higher throughput in a high mobility situation. Since radio bandwidth spectrum is limited, it is necessary to find techniques to increase spectral efficiency. The advent(More)
This paper presents a novel technique of image Enhancement which can be widely used in medical and biological imaging to improve the image quality. The principle objective of enhancement is to process an image so that the result is more suitable than the original image for a specific application.
