Two dimensional filters for enhancing the resolution of interpolated CT scan images

Abstract

This paper introduces new algorithms for enhancing the resolution of interpolated images. The aim of this algorithm is to have a high resolution image from a single low resolution image. The new algorithms used the interpolation technique with the two dimensional filter that is specifically designed for the image by maximizing the peak signal to noise ratio and structural similarity. The processed images are assessed by comparing them with the ground truth images. The algorithm performance is assessed using the peak signal to noise ratio (PSNR) and structural similarity (SSIM). The new algorithm gives better result than the previous 2D filters algorithms.
