Abstract:
The present invention determines, with high accuracy, a change having occurred in tissue. The present invention is provided with: a binarization unit (41) that generates, from an image of an analysis target, a plurality of binarized images having different binarization reference values; a Betti number calculation unit (42) that calculates, for each of the plurality of binarized images, a one-dimensional Betti number indicating the number of hole-shaped regions comprising pixels of a second pixel value surrounded by pixels of a first pixel value after being binarized into the first pixel value and the second pixel value; and a determination unit (44) that determines change having occurred in tissue on the basis of a binarization reference value in the binarized image in which the one-dimensional Betti number becomes maximum and on the basis of the number of one-dimensional Betti numbers in the binarized image.
