  • Publication number: 20240111804
    Abstract: A processor receives an input of finding information indicating at least one finding, which is desired to be searched for, on a query base image, which includes a part desired to be searched for and is a source of a query image, to derive the query image to which the finding has been added, derives at least one added finding feature amount indicating an image feature for the added finding, and derives a query normal feature amount indicating an image feature for a normal region included in the part in the query base image. The processor derives similarities between the query image and a plurality of reference images including findings on the basis of comparisons between the added finding feature amount and the query normal feature amount and the like with reference to an image database in which the plurality of reference images have been registered and extracts the reference image that is similar to the query image as a similar image from the image database on the basis of the similarities.

  • Publication number: 20220110505
    Abstract: 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.
