Object retrieval based on 3D weak geometric consistency

Abstract (in Japanese) (See Japanese page) 
(in English) The loss of geometric information about keypoints in BoW based object retrieval causes a precision degradation. 2D weak geometric consistency constraints were previously proposed to validate geometric information of keypoints. However traditional constraints fail when photos of 3D objects are taken from different angles because the 2D rotation differences of sampled keypoints are incoherent. To overcome this problem, we implement 3D weak geometric consistency constraints, which validate a consistency of view directions, into a BoW based object retrieval model.
