IMAGE SEARCH APPARATUS, METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image search apparatus capable of searching an image precisely representing an instance.SOLUTION: A precision calculation section 30 calculates a first image precision based on a collation result with a first feature vector of a feature point in an interest area; calculates a second image precision based on a collation result of a second feature vector of a feature point other than the interest area with respect to each of upper K images in the first image precision; and calculates a weighted linear sum of the first image precision and the second image precision as a ranking score.SELECTED DRAWING: Figure 1
