Abstract

A feature values definition input section inputs a feature values definition of object data used for retrieving. A feature values calculation section calculates feature values of object data previously stored in a database by using the feature values definition input by the feature values definition input section. An object data input/selection section inputs object data or previously selects object data from the database in which the object data is stored. A retrieval section retrieves similar object data from object data previously stored in the database by using the feature values of the object data input/selected by the object data input/selection section and the object data calculated by the feature values calculating section.
