ARTIFICIAL INTELLIGENCE SYSTEM AND METHOD FOR MODIFYING IMAGE ON BASIS OF RELATIONSHIP BETWEEN OBJECTSARTIFICIAL INTELLIGENCE SYSTEM AND METHOD FOR MODIFYING IMAGE ON BASIS OF RELATIONSHIP BETWEEN OBJECTS

An electronic device includes: a processor; and a memory storing instructions. By executing the instructions, the processor is configured to: receive a first image, recognize a plurality of objects in the first image to generate object information representing the plurality of objects, generate an object relationship graph including relationships between the plurality of objects, based on the first image and the object information, obtain image effect data including image effects to be respectively applied to the plurality of objects by inputting the object relationship graph to an image modification Graph Neural Network (GNN) model, and generate a modified image based on the first image, the object information, and the image effect data.
