Title:
IMAGE ANALYSIS METHOD, IMAGE ANALYSIS DEVICE, IMAGE ANALYSIS SYSTEM, IMAGE ANALYSIS PROGRAM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/102829
Kind Code:
A1
Abstract:
In order to accurately evaluate the degree of change that has occurred in a tissue, the present invention is provided with: a Betti number calculation unit (42) which generates, for one captured image of the tissue, a plurality of binarized images having different reference values used for binarization, and calculates, for each of the plurality of binarized images, a first feature number indicating the number of connected regions in which pixels having one of the binarized pixel values are connected; and a prediction score determination unit (44) for determining information relating to a change that has occurred in the tissue on the basis of the result of comparison between a pattern indicating a correlation between the reference value for binarization and the first feature number and a predetermined reference pattern.
