An image feature amount extraction unit and feature amount label matrix generation unit generate a label sequence from image data. An image management DB stores image data stored in an image storage unit and label sequences corresponding to the image data in correspondence with each other. A label sequence index registers, in units of labels, image data including the labels and the numbers of labels included in those image data. Upon search, a pattern matching unit extracts label sequences which are similar to the label sequence of a query image to some extent from the label sequence index, computes similarities between the extracted label sequences, and the label sequence of the query image, and outputs images, in which the computed similarities exceed a predetermined value, as search results. |

DETAILED DESCRIPTION The present invention has been made in consideration of the above problems, and has as its object to narrow down images that must undergo similarity computations with a query image to fewer images at high speed, and implement a high-speed similar image search.
It is another object of the present invention to attain a high-speed similar image search that takes the layout of image feature amounts into consideration.
It is still another object of the present invention to attain a similar image search that can search for a similar image in consideration of the layout of image feature amounts and can absorb differences due to variations of image sensing conditions and the like.
It is still another object of the present invention to achieve a quick similar image search by reducing the similarity computation volume by computing similarity between images in such a manner that a feature amount group is expressed by a single label, and an image is expressed by a label sequence or matrix.
It is still another object of the present invention to greatly improve the processing speed of an image search process using labels by appropriately managing a label sequence or matrix.
It is still another object of the present invention to attain a more effective similar image search using a method that permits certain ambiguity as to label position such as DP matching, fuzzy nondeterministic automaton, or the like upon determining similarity between a query image and an image to be compared by comparing label sequences or matrices.
It is still another object of the present invention to provide an image search apparatus or method which can attain a high-speed image search (or narrowing down) prior to or in place of an inner product computation of a color histogram.
It is still another object of the present invention to reduce the number of images to a value that the system can process by making a high-speed presearch using an index file.
It is still another object of the present invention to allow narrowing down in consideration of the ambiguity level of a search designated by the user
