Method and apparatus for retrieving similar objects

摘要

An object retrieval method used is characterized as follows. When a user selects objects, the dispersion between the objects is found with respect to each of a plurality of feature quantities. Within a retrieval range of objects, the dispersion between the objects is found with respect to each of a plurality of feature quantities. Both dispersions are compared for each feature quantity. As a result of the comparison, there may be a feature quantity which causes more converged dispersion in the selected objects. This feature quantity is provided with a weight larger than any other feature quantities to weight each feature quantity. An object is retrieved from the retrieval range based on the weighted feature quantities.
