Cross-Modal Retrieval

Cross-Modal Retrieval is the task of retrieving items from one modality using queries in a different modality — finding images that match a text description, finding audio clips that match a video scene, finding documents that match a photograph's content. The task depends on multimodal embeddings that place related items from different modalities near each other in a shared vector space. Real-world applications include reverse image search (Google Images, TinEye), visual product search in e-commerce ("find similar dresses"), audio-visual retrieval for media production, accessibility tools ("describe what this image shows"), and the retrieval phase of multimodal RAG systems that feed both text and images into vision-language models. Tools and models enabling cross-modal retrieval include CLIP, SigLIP, ImageBind, various proprietary multimodal APIs, and vector databases that index multimodal vectors. AI governance, AI compliance, and AI risk management programs deploy cross-modal retrieval with particular attention to content safety — supporting responsible AI through reviewed multimodal capabilities in enterprise AI environments worldwide.
