Their reconstruction quality, however, remains fundamentally limited by the geometry used for initialisation.","short_abstract":"Underwater 3D reconstruction supports applications ranging from marine ecosystem monitoring and subsea inspection to underwater archaeology, education, and immersive visualisation. 3D Gaussian Splatting has made real-time photorealistic novel-view rendering practical, while underwater variants incorporate physically ba...","url_abs":"https://arxiv.org/abs/2609.18737","url_pdf":"https://arxiv.org/pdf/2609.18737v1","authors":"[\"Harvey Caldeira\",\"Haoran Wang\",\"Guoxi Huang\",\"Shaoyu Cai\",\"Rachel Fu\",\"Nantheera Anantrasirichai\"]","published":"2026-09-16T14:32:58Z","proceeding":"cs.CV","tasks":"[\"cs.CV\"]","methods":"[]","has_code":false}
