A New Approach for Increase Resolution of satellite Image

By Sushma Lalwani and Uzma Ansari

Abstract

Abstract- This paper presents a new approach which is applied for increase or improved the quality of image of the highly bad focused satellite image. The main aim of this method is to increase resolution of satellite image by using resolution algorithm. The algorithm proposed in this paper is an automatic algorithm to pre-process such bad focused or corrupted satellite images. It reduces the effect of blur and noise and composed of several successive independent processing steps which suppress noise, enhance contrast, preserves the edge and increase the resolution of the image In this work, an effective method for image contrast enhancement is presented with a mapping function, which is a mixture of global and local transformation functions that improve both the brightness and fine details of the input image. Finally various image quality metrics were calculated for evaluating the performance of the proposed approach such as PSNR, MSE,SSIM etc
