Scene Graph Based Image Retrieval And Indexing

via “scene-graph-based-image-retrieval-and-indexing”

108K images with dense scene graphs and 5.4M region descriptions.

Unique: Provides 2.3M annotated relationships indexed as scene graphs, enabling structured retrieval by visual relationships and spatial configurations. Supports querying by relationship patterns (e.g., 'X on Y') rather than keyword matching, enabling semantic search over visual structure.

vs others: Enables relationship-based retrieval unlike keyword-based image search; supports complex spatial/semantic queries that text-based systems cannot express

📑 PageIndex: Document Index for Vectorless, Reasoning-based RAG

Unique: Integrates vision LLM processing into the indexing pipeline to extract semantic content from images and diagrams, treating visual elements as first-class nodes in the hierarchical tree rather than discarding them. Enables unified retrieval across text and visual content.

vs others: Handles multimodal documents more comprehensively than text-only RAG systems by extracting visual semantics and integrating them into the searchable index, rather than requiring separate image search or manual annotation.
