  • 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.

  • Patent number: 9390313
    Abstract: A partial image extracting unit extracts images of a predetermined size and constant magnification from a tissue region. A mask generating unit generates a mask for removing a region not intended for measurement from the tissue region for each extracted image. A complete mask generating unit generates a temporary complete mask in which the masks generated for each of the images are integrated together, and generates a complete mask in which close portions among unmasked portions in the temporary complete mask are unified into one or more target regions. A measuring unit measures information pertaining to an object to be measured included in the image, and this information is measured for each of the images extracted by the partial image extracting unit. A region information calculating unit calculates, for each target region, information pertaining to the object to be measured from the measured information and from the complete mask.

  • Publication number: 20140178874
    Abstract: Provided is a cancer evaluation method using a novel cancer marker for evaluating the onset, the preclinical stage, the clinical stage, or the prognosis of a cancer in a subject. At least one miRNA selected from hsa-miR-92 and hsa-miR-494 is used as the novel cancer marker in cancer evaluation. The cancer marker in a sample of a cell or a tissue is detected, and the possibility of a cancer in the sample is evaluated based on the expression level of the cancer marker. According to this evaluation method, by detecting the miRNA as the cancer marker, it becomes possible to evaluate the possibility of a cancer in the sample with excellent reliability. As a method for detecting the cancer marker, it is preferable to perform an in situ hybridization method using a labeled probe with respect to the sample that has been immobilized, for example.
