Publication number: 20240382064Abstract: An information processing apparatus (2000) detects an abnormal region (30) in each of a plurality of video frames (14) constituting video data (12) in which the inside of a body is captured. The information processing apparatus (2000) outputs output information related to the detected abnormal region (30). Herein, the information processing apparatus (2000) starts outputting of the output information when a detection score based on a proportion of the number of the video frames (14) in which the abnormal region (30) is detected becomes equal to or more than a first threshold value in a state where outputting of the output information is not being performed. Further, the information processing apparatus (2000) ends outputting of the output information when the detection score becomes equal to or less than a second threshold value in a state where outputting of the output information is being performed.Type: ApplicationFiled: July 30, 2024Publication date: November 21, 2024Applicants: NEC CORPORATION, NATIONAL CANCER CENTERInventors: Ikuma TAKAHASHI, Maki Sano, Kimiyasu Tokoh, Motoyasu Okutsu, Chiemi Tanaka, Masahiro Saikou, Hitoshi Imaoka, Kenichi Kamijo, Ryuji Hamamoto, Yutaka Saito, Masayoshi Yamada
