CoSAG: Compact Semantic Anchor Gaussians via Training-Free Rate-Distortion Coding
CoSAG is presented, which constructs the field without any per-scene training through a closed-form transmittance-weighted lift, spatially grounded semantic anchors, and multi-view denoising, and stores it with a spatially predictive entropy coder that ships no decoder.
