摘要

PROBLEM TO BE SOLVED: To accurately extract a lung region in a short time. SOLUTION: A threshold value processing part 101 binarizes input X-ray images by using a prescribed threshold value and a labeling part 102 labels the binarized images. Then, a lung region extraction part 103 extracts a region excluding the area less than a fixed area and prescribed areas in contact with the highest stage, lowest stage, most right stage and most left stage of the input images among the labeled areas and defines it as the lung region.
