1. A method of image enhancement, comprising: accessing first pixel data representative of a first image, the first pixel data including a number of pixels and the first pixel data being represented in a first domain, the first pixel data having a first array dimension corresponding to the number of pixels; conditioning first pixel data for edge refinement to generate edge-enhanced image data; transforming the edge-enhanced image data from the first domain into a second domain different from the first domain to generate transformed image data; upsampling the transformed image data based on an upsampling ratio to generate upsampled data; and transforming the upsampled data into the first domain to generate second pixel data, the second pixel data having a second array dimension greater than the first array dimension, the second array dimension corresponding to the upsampling ratio.
