A method of generating a high-resolution image from a set of source low-resolution images includes estimating a high-resolution image based on the set of source low-resolution images. The estimated high-resolution image is then transformed into a set of estimated low-resolution images. The set of source low-resolution images is compared with the set of estimated low-resolution images to generate a set of low-resolution errors. The set of low-resolution errors is transfomed into a set of high-resolution errors. A high-resolution error image based on the set of high-resolution errors is generated. The high-resolution error image is combined with the estimated high resolution image to yield an updated estimated high-resolution. The above steps are repeated until the updated estimated high-resolution image is of a desired quality.
