Electronic device and controlling method thereof

An electronic device comprising:

• a memory storing one or more instructions;
• and
• a processor configured to execute the one or more instructions to:
• obtain, from the memory, one or more artifact free images, and one or more artifacts represented by one or more artifact masks;
• obtaining a region of interest (ROI) mask identifying one or more ROIs in the one or more artifact free images;
• generate one or more transformed artifact masks by applying at least one localization parameter amongst a plurality of localization parameters to the one or more artifact masks;
• generate one or more localized artifact masks by placing the one or more transformed artifact masks on the ROI mask;
• and
• generate one or more artifact images by combining the one or more artifact free images and the one or more localized artifact masks.

A non-transitory computer-readable storage medium storing a program that is executable by a processor to perform a method of controlling an electronic device, the method comprising

• obtaining an artifact free image and an artifact mask identifying an artifact;
• obtaining a localized artifact mask by applying at least one localization parameter to the artifact mask and adjusting a position of the artifact mask to overlap with a region of interest (ROI) included in the artifact free image;
• and
• obtaining an artifact image by combining the artifact free image with the localized artifact mask.
