Method and electronic device for managing artifacts of image

An electronic device for processing image data, the electronic device comprising:

• a memory storing instructions;
• and
• a processor configured to execute the instructions to:
• receive an input image;
• extract a plurality of features from the input image, wherein the plurality of features comprise a texture of the input image, a color composition of the input image and edges in the input image;
• determine a region of interest (RoI) in the input image comprising at least one artifact based on the plurality of features;
• generate an at least one intermediate output image by removing the at least one artifact from the input image using a plurality of generative adversarial networks (GANs);
• generate a binary mask using the at least one intermediate output image, the input image, the edges in the input image and edges in the at least one intermediate output image;
• categorize the at least one artifact into a first artifact category or a second artifact category, based on the binary mask;
• and
• obtain a final output image from the input image based on a category of the at least one artifact that corresponds to the first artifact category or the second artifact category.

A non-transitory computer-readable storage medium storing a program that is executable by one or more processors to perform a method of processing image data, the method comprising:

• obtaining an input image;
• identifying types of artifacts included in the input image;
• generating a plurality of intermediate output images in which the artifacts are processed differently according to the types of the artifacts;
• generating a binary mask based on the plurality of intermediate output images and the input image;
• and
• applying the binary mask to the input image to selectively keep or remove the artifacts and to obtain a final output image in which at least one of the artifacts remains and another at least one of the artifacts is removed.
