    Abstract: Plural pieces of data where N (N>2) elements are arranged in a predetermined-direction in a specific-order are sorted into any one of N labels using a graph-cut-process. Each of the plural pieces of data has scores indicating element-likenesses for the plural respective elements. For each piece of data, weights are set about links along a first-direction directing from a node s to a node t so that a small weight is given to a link corresponding to an element having a maximum-score in the data. A weight for regulating cutting is set about links along a second-direction opposite to the first-direction and links along a direction in which the order of the respective pieces of data progresses. A graph-cut-process is executed on a graph for which the weights are set to determine links to be cut, and the N labels are allocated to the plural pieces of data.

    Abstract: A first-image and a second-image representing the same organ of the same subject imaged at the same time are obtained, and an organ-region is extracted from the first-image. The extracted organ-region is displayed on a display screen. An input of an air-region included in the first-image and an input of exceeding or lacking portion information representing that the air-region is a lacking portion or an exceeding portion of the organ are received, and the received air-region and the received exceeding or lacking portion information corresponding to the air-region are obtained, as correction information. Corresponding positions are matched with other between the first-image and the second-image. The organ-region extracted from the first-image is corrected based on the correction information. At least an air-region in the second-image located at a position corresponding to the air-region corresponding to the correction information is extracted, as a part of the organ-region in the second-image.
