Revising similarity relationship hashing for unsupervised cross-modal retrieval

You Wu, Bo Li, Zhixin Li

Abstract: Highlights•We propose a cross-modal hash retrieval method for similarity relation updating.•A multimodal fusion similarity graph extends the similarity boundaries.•Feature cross reconstruction module enhances heterogeneous modal interaction.•Similarity graph update module corrects inaccurate similarity matrix values.•Experimental results show the superiority of proposed RSRH method.
