Abstract
In this article, we propose a new method that achieve super resolution of an image which uses a channel wise gradient descent approach to obtain high resolution version image from low resolution version of the image. In this technique we first apply bilinear interpolation further divides the low resolution colour image in to R, G, B channels then apply the gradient decent approach to individual channel by using a set of rules and finally producing the high resolution image. The proposed approach provides high PSNR value and relative SSIM as compared to the existing methods.
