Abstract
A method and system () generates an output image () of increased pixel resolution from an input image (), which is non-dyadically upscaled to generate an upscaled image () having more pixels than the input image and is low-pass filtered to generate a smoothed image (). A high detail image () is generated by subtraction and for each pixel in the upscaled image, a patch () containing the pixel is identified. A best-fit patch () within a localized region () of the smoothed image is found by searching in the smoothed image in close proximity to a mapped location of the patch in the upscaled image. Each pixel in the patch of the upscaled image is corrected by uniquely adding the value of the corresponding pixel in an equivalent patch of the high detail image corresponding to the best-fit patch, and the corrected upscaled image is stored for further processing.
