<p>A hierarchical method derives a content-based image tree from a database (52) set of multiple images, each image having an associated feature metric. The method partitions the set of multiple images into a first subset and a second subset by allocating images to each subset whose feature metrics are closer to a feature metric of a seed image in each respective subset (step 36); selects for each subset a comparison image whose feature metric is representative of feature metrics of images partitioned into the respective subsets (step 40); and recursively repeats the above steps for each subset, subsets of each subset, etc. to create a tree of partitioned subsets of images (step 42). The method then enables a search based on the comparison images. <IMAGE></p> |
