Grouping Technique for Cooperative Spectrum Sensing in Cognitive Radios

Rizwan Akhtar, Adnan Rashdi and Abdul Ghafoor
Electrical Engineering Department, College of Signals, National University of Science & Technology, Pakistan


Abstract

Cognitive networks can potentially solve the
problems of spectrum scarcity by accommodating unlicensed
(secondary) users in under-utilized segments of the spectrum.
Spectrum sensing serves as the primary stimulus for a cognitive
radio and is vitally impor ....etc

image detail enhancement using a dictionary technique

Abstract

We present a novel approach to detail enhancement using a dictionary-based technique. For each low-resolution input image patch, we seek a sparse representation from an over-complete dictionary and use that to estimate the high-resolution patch. We modify an existing dictionary-based super-resolution method in several ways to achieve enhancement of fine detail without introduction of new artifacts. These modifications include adaptive enhancement of reconstructed detail patches ba ....etc

Light scattering and color change are two major sources of distortion for underwater photography. Light scattering is caused by light incident on objects reflected and deflected multiple times by particles present in the water before reaching the camera. This in turn lowers the visibility and contrast of the image captured. Color change corresponds to the varying degrees of attenuation encountered by light traveling in the water with different wavelengths, rendering ambient underwater environments dominated by a bluish tone. No existing underwa ....etc

Abstract
In this paper, we propose a method of image resolution enhancement using a single image. The proposed method enhances the resolution by emphasizing the high frequency of a magnified low resolution image. Experimental results show that the performance of our method has been improved by 13%-25% over the conventional interpolation methods.
I. INTRODUCTION
Recently, many users require high resolution images as applications and demands for high quality images are increasing. Moreover, we often transfer images by using mob ....etc
