Title:
METHOD, ELECTRONIC DEVICE, AND STORAGE MEDIUM FOR PROCESSING IMAGE BY USING CONVOLUTION NEURAL NETWORK
Document Type and Number:
WIPO Patent Application WO/2023/211000
Kind Code:
A1
Abstract:
Provided are a method, electronic device, and storage medium for processing an image by using a convolution neural network. The method comprises the steps of: generating an up-scaled image by up-scaling an input image; obtaining a first feature map and a second feature map by performing a convolution operation between the up-scaled image and one or more kernels included in the convolution neural network, by inputting the up-scaled image to the convolution neural network; obtaining a gain map by inputting the first feature map to a first convolution layer; obtaining an offset map by inputting the second feature map to a second convolution layer; and generating an output image on the basis of the up-scaled image, the gain map, and the offset map, wherein the convolution neural network is trained to reduce a color difference between the input image and the output image.
