Comprehensive-perception dynamic reasoning for visual question answering

•The proposed comprehensive-perception dynamic reasoning model can perceive all the object features from the previous reasoning process.•The introduction of relation network as a guide for interaction between features enhances the relational reasoning capability of the model.•Employing intra- and inter-layer attention weights optimizes the importance of object features in the reasoning process.•Incorporating our CPDR module into the VLP models brings considerable performance improvements.
