Dynamic-Robust Photometric-Semantic Reconstruction for Open-Vocabulary 3D Scene Understanding

SPAR is proposed, a novel joint semantic-geometric encoding architecture that explicitly isolates transient dynamic noise prior to latent space aggregation that structurally couples motion estimation with multi-view visual and semantic learning and reveals a strong inter-task synergy between photometric scene reconstru...

SRA-Det: Learning Omni-Grained Open-Vocabulary Detection Beyond Category Names

A Semantic-Retrieval-Augmented Detector (SRA-Det) is proposed that uses an attention-based module to retrieve multiple semantic facets from token-level text features, and a soft-min matching rule that behaves like a differentiable logical AND over these facets, ensuring that all key attributes are satisfied.
