IMAGE ANALYSIS METHOD, IMAGE ANALYSIS PROGRAM, RECORDING MEDIUM, IMAGE ANALYSIS DEVICE, AND IMAGE ANALYSIS SYSTEM

摘要

According to the present invention, an assessment is made in an objective and appropriate manner as to whether canceration has occurred in cells reflected in an image, the type of cancer, etc., by analyzing an image of a cell sample. This image analysis device (1) comprises: a binarization unit (41) that performs a binarization process a plurality of times on one captured image while varying a binarization reference value, thereby generating a plurality of binarized images; a Betti number calculation unit (42) that calculates, for each of the generated plurality of binarized images, a region number that is the number of hole-shaped regions; and a cancer assessment unit (43) that assesses the type of cancer in cells included in tissue, the assessment being made on the basis of the binarization reference value of the binarized image when the region number matches a prescribed value.
