Ov3R: Open-Vocabulary Semantic 3D Reconstruction from RGB Videos

CVPR 2026

We present Ov3R, a novel framework for open-vocabulary semantic 3D reconstruction from RGB video streams, designed to advance Spatial AI. The system features two key components: CLIP3R, a CLIP-informed 3D reconstruction module that predicts dense point maps from overlapping clips alongside object-le

PANKRAG: ENHANCING GRAPH RETRIEVAL VIA GLOBALLY AWARE QUERY RESOLUTION AND DEPENDENCY-AWARE RERANKING MECHANISM

ICASSP 2026poster

Recent graph-based RAG approaches leverage knowledge graphs by extracting entities from a query to fetch their associated relationships and metadata. However, relying solely on entity extraction often results in the misinterpretation or omission of latent critical information and relationships. This…
