Supervised adaptive similarity matrix hashing
Webhash codes are learned in an unsupervised way and label information is not fully considered. Moreover, the preservation of intra-modal similarity is not taken into account. To address these issues, we propose a supervised cross- modal hashing approach named Supervised Matrix Factoriza- tion Hashing (SMFH).
