Title:
画像検索装置および画像検索方法
Document Type and Number:
Japanese Patent JP4777059
Kind Code:
B2
Abstract:
It is an object of the invention to provide an image search apparatus and image search method in which, even when a large amount of multidimensional feature data such as the face/color exists in high dimensions, an image desired by the user can be searched efficiently and adequately. The image search apparatus of the invention has:
dimension reducing means 102 for reducing dimensions of multidimensional feature data to be produces as approximate data;
approximate-data storing means 103 for storing the produced approximate data with corresponding to the multidimensional feature data before the dimension reduction;
search request receiving means 104 for receiving an identifier which identifies multidimensional feature data of a person to be searched, at least as a search key;
approximate-space searching means 105 for calculating distances between approximate data corresponding to the received search key, and plural approximate data stored in the approximate-data storing means 103, and for arranging the distances in order of similarity; and
real-space final ranking means 106 for again performing a distance calculation with using the multidimensional feature data before the dimension reduction, on a group of results in which the similarity is high, and for determining final rankings.
