Abstract: Highlights•Dual consistency preserving is designed: semantic consistency and learning process consistency.•Semantic consistency is explored by continuous semantic labels and fine-grained similarity graph.•Learning process consistency is preserved through a modality deviation calibration mechanism.•Extensive experiments demonstrate the superiority of DOCMH.
