Publication number: 20220375033Abstract: A deep feature generation unit (20) inputs an inference image from an input layer (21) of a neural network, performs forward propagation in the neural network, and outputs a plurality of frame images that each include a channel image and are aligned in a predetermined first sequence as intermediate output values from an intermediate layer (22), which is a predetermined layer that is not an output layer of the neural network. A rearrangement unit (30) rearranges the frame images aligned in the first sequence into frame images in a second sequence based on a predetermined rearrangement sequence from the first sequence to the second sequence, such that a total of degrees of similarity between adjacent frame images in the second sequence is greater than a total of degrees of similarity between adjacent frame images in the first sequence.Type: ApplicationFiled: November 15, 2019Publication date: November 24, 2022Applicants: NIPPON TELEGRAPH AND TELEPHONE CORPORATION, NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Satoshi SUZUKI, Motohiro TAKAGI, Ryuichi TANIDA, Mayuko WATANABE, Hideaki KIMATA
