Title:
IMAGE RETRIEVAL DEVICE AND IMAGE RETRIEVAL METHOD
Document Type and Number:
WIPO Patent Application WO/2007/072947
Kind Code:
A1
Abstract:
Image retrieval device and method are provided with a feature in which an image
desired by a user can be efficiently and adequately retrieved even in the case
that there is a great volume of multidimensional characteristic data of face/color,
etc. The image retrieval device comprises a dimensionality reduction means
(102) for reducing a dimensionality of the multidimensional characteristic
data to generate approximating data, an approximating data storing means (103)
for storing generated approximating data corresponding to the multidimensional
characteristic data before the dimensionality reduction, a retrieval request
receiving means (104) for receiving an identifier to identify multidimensional
characteristic data of persons subjected to retrieval at least as a retrieval
key, an approximating space retrieval means (105) for calculating a distance
between approximating data corresponding to a received retrieval key and a plurality
of approximating data stored in the approximating storing means (103) and setting
out calculated results in similarity order, and a real space final ranking means
(106) for calculating a distance again by using the multidimensional characteristic
data before the dimensionality reduction with respect to a higher similarity
result group and determining a final rank.
