発明の名称 (英語) METHOD FOR CREATING IMAGE DATABASE FOR OBJECT RECOGNITION, PROCESSING DEVICE, AND PROCESSING PROGRAM 新技術説明会
発明の概要(英語) Provided is a method for creating an image database for object recognition, which comprises a feature extraction step of extracting local descriptors from object images which are to be registered in an image database, a scalar quantization step of quantizing a numeric value indicating each dimension of each of the local descriptors into a predetermined number of bit digits, and a registration step of systematizing each of the local descriptors after the quantization to be able to be searched for in the closest vicinity, giving to the local descriptor an identifier of the image from which the local descriptor has been extracted, and registering the local descriptor to which the identifiers are given in the image database. The registration step comprises extracting the local descriptors from the object images when a search query is given, scalar-quantizing each dimension, determining a local descriptor in the closest vicinity of each of the local descriptors from the image database, and performing registration so as to be able to identify one image by majority vote processing from the images including any determined local descriptor. The scalar quantization step comprises quantizing each dimension of each of the local descriptors into 8 bits or less. Also provided are a processing program for the method and a processing device for performing the processing.
