Up Sampling of an Image Using Convolution Method

In this paper, we propose an effective method of up sampling using convolution by interpolating the pixels. Quality needs to be preserved as it gets affected when re sampling is done. Resampling is interpolating a discrete image and continuous image and then sampling of the interpolated image is done. In this paper the image quality is compared using different interpolation key methods like bilinear, nearest neighbour and bucolic using image quality index. The comparison of RMSE and PSNR values is done for up sampled images and found to have minimum value for the up sampling using convolution method. The results on images, based on method proposed, has been shown. From outcome, it is very imperative to say that the proposed method succeeded in its aim to have better image quality index for up sampling.
