Abstract
To divide appropriately an image including cells into a plurality of types of regions in accordance with image features, the image processing method of the invention includes acquiring an original image which includes a cell which is cultured, dividing the original image into blocks each of which consists of a predetermined number of pixels and obtaining spatial frequency components that an image in each block has, classifying each of the blocks into a plurality of clusters in a multi-dimensional feature value space in which intensity of a DC component among the spatial frequency components and intensity of each of a plurality of AC components which are different in a spatial frequency from one another are regarded as feature values; and dividing the original image into a plurality of regions on the basis of a result of the classification.
