Abstract
A method for processing an image includes receiving an input image including a signal and noise, and generating a filtered image based on the input image by removing at least a portion of the noise from the input image. A portion of the signal is also removed from the input image. The method further includes generating a residual image based on the input image. The residual image comprises the at least a portion of the noise and the portion of the signal that are removed from the input image to generate the filtered image. The method also includes identifying at least some of the portion of the signal that is in the residual image, and inserting the at least some of the portion of the signal identified in the residual image into the filtered image.
