Abstract
A method of processing an image for improving image quality is provided. The method includes inputting an image into a first artificial neural network as an input variable to create a feature map and inputting an image into a second artificial neural network as an input variable to create an estimated class probability distribution map for each of frequency channels. Further, the method may comprise determining a class for each of the frequency channels on the basis of a probability distribution included in the estimated class probability distribution map, creating an estimated class map that includes a determined class, converting the estimated class map into an estimated frequency map, combining the estimated frequency map with the feature map to create a combined feature map, and inputting the combined feature map into a third artificial neural network as an input variable to create an output image.
