Image processing apparatus and image processing method, and recording medium for processing breast image based on local contrast values in a local region in a mammary gland region of breast image
An image processing apparatus includes: an image obtaining device which obtains a breast image obtained by radiography of a breast; a mammary gland region extracting device which extracts a mammary gland region from the breast image; a local region setting device which sets a plurality of local regions around pixels belonging to the extracted mammary gland region; a local contrast value calculating device which calculates a plurality of local contrast values in a local regions, for each of the set plurality of local regions; and an image processing device which applies image processing to the breast image on the basis of the calculated plurality of local contrast values. Thus, considering a contrast between a mammary gland and a fat region, a stable image processing result can be obtained while enhancing viewability of a local mammary gland structure and a lesion.
