Image retrieval system, image retrieval program and storage medium and image retrieval method
First Claim
1. An image retrieval system for retrieving an image corresponding to a retrieval key among plural images subject to retrieval based on the retrieval key, the image retrieval system comprising:
- a retrieval subject image storing unit that stores the images subject to retrieval so that respective images correspond to first characteristic information and second characteristic information among semantic characteristic information corresponding to a categorical attribute given in accordance with contents of an image, physical characteristic information relating to at least one of a size of an image and an arrangement of colors in an image and prominence characteristic information showing prominence of an image;
a retrieval key inputting unit that inputs the first characteristic information and the second characteristic information as the retrieval key;
a characteristic information converting dictionary storing unit that stores a characteristic information converting dictionary defining a corresponding relation between the semantic characteristic information, the physical characteristic information and the prominence characteristic information;
a characteristic information converting unit that obtains a remainder of the characteristic information other than any two of the semantic characteristic information, the physical characteristic information and the prominence characteristic information based on the two of the semantic characteristic information, the physical characteristic information and the prominence characteristic information, and that retrieves the remainder of the characteristic information from the characteristic information converting dictionary based on the given two pieces of characteristic information; and
an image retrieval unit that retrieves an image subject to retrieval, the image at least being approximate to third characteristic information other than the first characteristic information and the second characteristic information among the semantic characteristic information, the physical characteristic information and the prominence characteristic information, from the retrieval subject image storing unit by the characteristic information converting unit based on the first characteristic information and the second characteristic information, which are inputted by the retrieval key inputting unit.

Abstract
An image retrieval system including: a retrieval subject image storing unit storing images corresponding to first and second characteristic information among semantic characteristic information, physical characteristic information and prominence characteristic information; a retrieval key inputting unit inputting the first and second characteristic information as the retrieval key; a characteristic information converting unit obtaining remaining characteristic information, the physical characteristic information and the prominence characteristic information based on the two semantic characteristics, the physical characteristic and the prominence characteristic information; and an image retrieval unit retrieving an image matching or being approximate to third characteristic information other than the first and second characteristic information among the semantic characteristic, the physical characteristic and the prominence characteristic information, from the retrieval subject image storing unit by the characteristic information converting unit based on the first and second characteristic information, which are inputted by the retrieval key inputting unit.

4. A computer-readable medium storing an image retrieval program for retrieving an image corresponding to a retrieval key among plural images subject to retrieval based on the retrieval key, the image retrieval program being a program causing a computer to execute a process comprising:
-
a retrieval key inputting step for inputting as the retrieval key first characteristic information and second characteristic information among semantic characteristic information corresponding to a categorical attribute given in accordance with contents of an image, physical characteristic information relating to at least one of a size of an image and an arrangement of colors in an image, and prominence characteristic information showing prominence of an image; a characteristic information converting step for obtaining a remainder of the characteristic information other than any two of the semantic characteristic information, the physical characteristic information and the prominence characteristic information based on the two of the semantic characteristic information, the physical characteristic information and the prominence characteristic information, by retrieving the remainder of the characteristic information from a characteristic information converting dictionary based on the given two pieces of characteristic information, the characteristic information converting dictionary defining a corresponding relation between the semantic characteristic information, the physical characteristic information and the prominence characteristic information; and an image retrieval step for carrying out the characteristic information converting step based on the first characteristic information and the second characteristic information, which are inputted in the retrieval key inputting step, to retrieve an image subject to retrieval, the image at least being approximate to third characteristic information other than the first characteristic information and the second characteristic information among the semantic characteristic information, the physical characteristic information and the prominence characteristic information, from a retrieval subject image storing unit stored with respective images subject to retrieval, the images corresponding to the first characteristic information and the second characteristic information.
