ELECTRONIC APPARATUS AND CONTROL METHOD THEREOF

Document Type and Number:

WIPO Patent Application WO/2023/163494

Kind Code:

A1

Abstract:

Disclosed is an electronic device. The electronic device comprises: a memory for storing a trained neural network model; and a processor that inputs an input image to the trained neural network model and thereby acquires a quality score of the input image, a quality score for each pixel included in the input image, and a region of interest (ROI) score for each of the pixels. The trained neural network model comprises: a first neural network module that acquires first feature information for each of the pixels included in the input image; a second neural network module that acquires second feature information for each of the pixels included in the input image; a third neural network module that acquires the quality score for each of the pixels included in the input image on the basis of third feature information that combines the first feature information and the second feature information; a fourth neural network module that acquires the ROI score for each of the pixels on the basis of fourth feature information that combines the first feature information and the second feature information; and an operation module that acquires the quality score of the input image on the basis of the quality score for each of the pixels and the ROI score for each of the pixels.
