Title:
ELECTRONIC APPARATUS AND CONTROLLING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/141210
Kind Code:
A1
Abstract:
A controlling method of an electronic apparatus may include: obtaining image data and metadata regarding the image data, the image data comprising a first image frame and a second image frame that is subsequent to the first image frame; obtaining information regarding a region of interest of the first image frame by inputting the first image frame to a first neural network model; obtaining a similarity between the first image frame and the second image frame based on motion vector information included in the metadata; and detecting whether there is a manipulated area in the second image frame based on the similarity.
