A conference attendee is closely examining a poster presentation titled "LEGaussians: Language Embedded 3D Gaussians." The poster, displayed on a black frame, is authored by Jin-Chuan Shi, Miao Wang, and others, representing the State Key Laboratory of Virtual Reality Technology and *Beihang University*. The content highlights the integration of language embeddings with 3D Gaussian representations to enhance novel view synthesis in 3D scenes. The background, motivation, and methodology sections are outlined, with specific emphasis on the benefits and challenges of embedding language features in 3D scene representations. The colorful diagrams and illustrations on the poster provide visual insight into their approach. The attendee, sporting a navy blue cap and carrying a black backpack, seems deeply engaged with the material, indicative of an academic or professional interest in virtual reality and language processing technologies presented at the event.

NeRFs and 3DGS enhance novel view synthesis from multi-view images by capturing geometric and appearance details of 3D scenes. Language-embedded scene representations based on NeRF heavily depends on MLPs that are resource-intensive in training and rendering. Motivation 3D Gaussians offer efficient and high-quality novel view synthesis directly embed language features in them leads to huge memory usage and decreased performance LEGaussia Language Embedde 3D Gaussians semantics uncertainty Adaptive Spatial Smoothing ➤ Or position semantics Sigmo uncertainty ງ Multi-view Images DINO CLIP Language-embedded 3D Gaussians Multi-view Features We introduce LEGaussians: Language Embed scene representation for open-vo mization and rende nd acc
