ABSTRACT:
Information regarding the line segments constituting a line figure is input from an input section. An initial degree of certainty with respect to the attribute of each of the line segments is calculated by a degree of certainty-calculating section, on the basis of the information input from the input section. How the line segments are connected to other line segments is detected by a connection-detecting section. A compatible coefficient is determined by a degree of certainty-updating section in accordance with the connection detected by the connection-detecting section. By repeatedly executing calculation on the basis of the compatible coefficient, the initial degree of certainty calculated by the degree of certainty-calculating section is updated. Based on the updated degree of certainty, the attributes of the line segments are determined.
