  • Patent number: 8311320
    Abstract: A difference emphasizing apparatus aligns a first three-dimensional model and a second three-dimensional model in orientation and position in accordance with a predetermined rule, and gets data of respective apices of the first three-dimensional model and the second three-dimensional model. Based on the gotten data, the apparatus finds a corresponding point on the first three-dimensional model, which corresponds to the apex of the second three-dimensional model in a direction of a particular axis. When the corresponding point is detected, the apparatus calculates a difference between the first three-dimensional model and the second three-dimensional model in the direction of the particular axis based on the corresponding point and the apex of the second three-dimensional model. The apparatus enlarges the difference in the direction of the particular axis, and calculates a position of the apex of the second three-dimensional model after the enlargement.

  • Patent number: 8275780
    Abstract: A rule discovery program which enables discovery of a rule by automatically searching for a feature portion which is effective for generation of a rule in multimedia data. When sample data items are inputted, a search unit selects evaluation positions on a data array constituting each of the sample data items so as to generate a selection pattern. Next, an integration unit integrates the evaluation positions in the selection pattern so as to generate a predetermined number of evaluation regions, and a rule-candidate generation unit generates a rule candidate indicating a relationship common to the sample data items. A rule-candidate evaluation unit evaluates the generated rule candidate, and an output unit outputs, as a rule, the rule candidate when the rule candidate satisfies a predetermined criterion.
