Pseudo Perfect Coding for Discrete Cross-modal Hashing
Yusuke Masuda, Gou Koutaki (Kumamoto Univ.) PRMU2020-16
Abstract (in Japanese) (See Japanese page) 
(in English) Recently, cross-modal hashing has attracted attention in the field of image processing.
Compressing data which have different medias and same classes into the same hash codes with this method enables high-speed cross-modal search. HC-DCH (Hadamard Coding for Discrete Cross-modal Hashing) is one of the methods. To clarify the classification of classes, HC-DCH uses an orthogonal matrix called Hadamard matrix. However, we propose a hashing method using pseudo perfect codes whose Hamming distance of each classes are bigger than one of Hadamard matrix. We confirmed the values of mAP of proposed method than one of HC-DCH in the experiment.
