Title:
METHOD AND DEVICE FOR PROCESSING IMAGE FOR QUALITY IMPROVEMENT OF IMAGE
Document Type and Number:
WIPO Patent Application WO/2019/147020
Kind Code:
A1
Abstract:
The present invention relates to a method for processing an image for improving image quality, which is driven on a computing device. The method comprises the steps of: 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. In addition, the method can further comprise the steps of: determining a class for each of the frequency channels on the basis of a probability distribution included in the estimated class probability distribution map and creating an estimated class map including 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.
