BOF EXPRESSION GENERATION DEVICE AND BOF EXPRESSION GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a device or a method for generating BoF expression capable of performing accurate image retrieval.;SOLUTION: Distances between i-th subject local feature quantity on an object image and a plurality of clusters are calculated respectively. Then, a plurality of clusters that are relatively closer to the i-th subject local feature quantity than other clusters are determined. The BoF expression corresponding to the object image is generated using ID information of the plurality of determined clusters.;COPYRIGHT: (C)2014,JPO&INPIT
