<P>PROBLEM TO BE SOLVED: To accurately construct a plurality of network structures corresponding to a plurality of constructs from medical image data. <P>SOLUTION: A likelihood of a cross segment representing a probability that each segment is a cross segment is calculated based on a cross segment characteristic condition defining a characteristic that a portion corresponding to an intermingled portion of a construct is present as a cross segment, and that at least two pairs of segments connectable to form a straight line with each other are present in the neighborhood of the cross segment, in the plurality of segments. A likelihood of a straight line representing a probability that each segment is connected, in a straight line, to another segment is calculated based on a straight line connection condition defining a characteristic that each segment is connected to form a straight line to another segment in the neighborhood of each segment. Strength of connection between the respective segments is set using the likelihood of a cross segment and the likelihood of a straight line, and a plurality of networks are constructed by connecting the respective segments based on the connection strength. <P>COPYRIGHT: (C)2013,JPO&INPIT |
