1. A method for processing one or more reconstructed images, comprising: receiving a first reconstructed image having a first image resolution; receiving a second reconstructed image having a second image resolution, wherein the first resolution is greater than the second resolution; generating a gradient map based at least on the second reconstructed image; transforming the gradient map with a function that ensures smooth weighting transitions; generating a weighting function based on the transformed gradient map; and generating a contrast-dependent resolution image by combining, based on the weighting function, the first and second reconstructed images into a single image so that the first reconstructed image contributes to a greater degree to the contrast-dependent resolution image for higher contrasts regions of the images and the second reconstructed image contributes to a greater degree to the contrast-dependent resolution image for lower contrasts regions of the images.
