ADDING METADATA APPARATUS
First Claim
1. An adding metadata apparatus comprising:
- a first acquisition unit which acquires a first image, first metadata, and a first position within the first image, the first position being for displaying the first metadata;
an extraction unit which extracts local features from the first image;
a calculation unit which searches for a group of the local features within a predetermined distance from the first position, and calculates a representative point of the group;
a search unit which matches the first image with a plurality of images stored in a database by using the local features, and searches for a second image which coincides with the local features; and
a registration unit which calculates a second position, within the second image, corresponding to the representative point, and registers the second position and the first metadata as metadata for the second image.

Abstract
An adding metadata apparatus includes a first acquisition unit which acquires a first image, first metadata, and a first position within the first image, the first position being for displaying the first metadata; an extraction unit which extracts local features from the first image; a calculation unit which searches for a group of the local features within a predetermined distance from the first position, and calculates a representative point of the group; a search unit which matches the first image with a plurality of images stored in a database by using the local features, and searches for a second image which coincides with the local features; and a registration unit which calculates a second position, within the second image, corresponding to the representative point, and registers the second position and the first metadata as metadata for the second image.

8. An adding metadata method comprising:
-
acquiring a first image, first metadata, and a first position within the first image, the first position being for displaying the first metadata; extracting local features from the first image; searching for a group of the local features within a predetermined distance from the first position, and calculating a representative point of the group by a calculation unit; matching the first image with a plurality of images stored in a database by using the local features, and searching for a second image which coincides with the local features; and calculating a second position, within the second image, corresponding to the representative point, and registering the second position and the first metadata as metadata for the second image. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An attaching metadata method comprising:
-
acquiring a first image, metadata to be attached to the first image and a target position of the first image into which the metadata is attached; extracting local features of the first image searching a model image having the local features similar to the local features extracted from the first image acquiring a group of local feature points around the target point in the first image; obtaining the local feature points in the model image searched as similar, said local future points corresponding to the group of local feature points in the first image; and attaching the metadata of the first image at the local feature points in the model image as metadata for the second image, said local feature points obtained by said obtaining step. - View Dependent Claims (16)
