Abstract: Highlights•Structure-aware pairing using image fingerprints to address over-centralized issues.•A novel model to consolidate hierarchical embeddings for representation learning.•Addressing ill-posed gradient issues introduced by relaxed Hamming distance.•A self-supervised OOD detection module by evaluating image reconstruction disparity.•Content-guided ranking mechanism for robust and precise retrieval.
