A server includes: a memory; and a processor coupled to the memory and configures to: receive a frame image of a moving image compressed by an information processing device; detect a sign of deterioration in analysis accuracy based on accuracy information that represents certainty of an analysis result by artificial intelligence for the frame image; transmit, to the information processing device, instruction information of controlling a compression rate in compression of the moving image by the information processing device between an upper bound and a lower bound; and change the upper bound and the lower bound according to stability of the analysis accuracy based on the detection of a sign of deterioration in the analysis accuracy.

Server, control method, and computer-readable recording medium storing control program

An analysis method implemented by a computer includes: generating a refine image by changing an incorrect inference image such that a correct label score of inference is maximized, the incorrect inference image being an input image when an incorrect label is inferred in an image recognition process; and narrowing, based on a score of a label, a predetermined region to specify an image section that causes incorrect inference, the score of the label being inferred by inputting to an inferring process an image obtained by replacing the predetermined region in the incorrect inference image with the refine image.
