Instead of a binary keep-or-discard call on each frame, it uses Reliability-aware View Allocation to grade every frame on appearance quality, degradation risk, and geometric usefulness, then weights its contribution to the reconstruction accordingly, while pulling back in weak-but-useful frames to preserve camera-path coverage. For damage that weighting alone can't fix, like motion blur, it runs Render-Guided In-Video Restoration: it compares the current 3D render, a restored version of the raw footage, and a high-frequency blend of both, then keeps whichever scores best on no-reference perceptual metrics. A final pass, Full-Trajectory Repair Consolidation, revisits earlier fixes so early-frame detail doesn't get lost later in the process. On the GS2E and GSOTM benchmarks, ClearGS posted state-of-the-art results on CLIP-IQA and MUSIQ image-quality scores and lower LPIPS error in most degradation cases, without ever using paired sharp footage or matched clean reference images.\n\nMost 3DGS research still assumes tripod-steady, well-lit capture, which is not how anyone actually films a room on their phone. ClearGS targets the real failure mode - shaky, uneven, partly blurry footage - rather than a lab-clean input, which matters for any product trying to turn a walkthrough video into a usable 3D model.\n\nThe gains are measured against curated benchmark datasets, not a pile of random phone clips, and the paper is silent on how much extra compute all this reliability-grading and restoration costs per frame.","[\"gaussian-splatting\",\"3d-reconstruction\",\"computer-vision\",\"ai-research\"]","2026-09-28T04:00:00.000Z","2026-09-28T08:36:36.701Z","2026-09-28T08:36:43.729Z","published",null,[],"ai",[26,27,28,29],"gaussian-splatting","3d-reconstruction","computer-vision","ai-research",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.31509",0,{"sections":36},[37,40,44,49,54,59,63,68,73,78,83,88,92,97],{"name":38,"slug":24,"count":39,"latest_published_at":18},"AI",4791,{"name":41,"slug":42,"count":43,"latest_published_at":18},"Security","security",762,{"name":45,"slug":46,"count":47,"latest_published_at":48},"Policy","policy",399,"2026-09-27T18:39:02.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Deals","deals",261,"2026-09-27T15:30:35.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Hardware","hardware",188,"2026-09-27T20:46:36.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":18},"Science","science",151,{"name":64,"slug":65,"count":66,"latest_published_at":67},"Consumer Tech","consumer-tech",135,"2026-09-26T14:30:00.000Z",{"name":69,"slug":70,"count":71,"latest_published_at":72},"Software","software",91,"2026-09-25T20:55:00.000Z",{"name":74,"slug":75,"count":76,"latest_published_at":77},"Dev Tools","dev-tools",84,"2026-09-26T04:20:58.000Z",{"name":79,"slug":80,"count":81,"latest_published_at":82},"Startups","startups",76,"2026-09-25T18:33:59.000Z",{"name":84,"slug":85,"count":86,"latest_published_at":87},"Gaming","gaming",48,"2026-09-25T18:35:21.000Z",{"name":89,"slug":90,"count":86,"latest_published_at":91},"General","general","2026-09-26T17:02:42.000Z",{"name":93,"slug":94,"count":95,"latest_published_at":96},"Reviews","reviews",30,"2026-09-24T20:07:31.000Z",{"name":98,"slug":99,"count":100,"latest_published_at":101},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
