It works blind, with no calibrated acoustic priors, and beats a baseline that was handed the true sound speed.researchTue, 01 Sep 2026 01:30:00 GMThttps://splats.com/2026/08/31/abcd-constant-vram-block-descenthttps://splats.com/2026/08/31/abcd-constant-vram-block-descentABCD freezes all but one spatial block and collapses everything else into two flat images, exploiting the fact that alpha blending is associative. Peak VRAM becomes constant in scene extent — but on the two scenes measured it saved 15%, tripled system memory and took twelve times as long.researchMon, 31 Aug 2026 18:50:00 GMThttps://splats.com/2026/08/29/fixanything-video-prior-any-representationhttps://splats.com/2026/08/29/fixanything-video-prior-any-representationCMU's FixAnything cleans up renderings from NeRF, 3DGS, mesh or sparse SfM points with a single video model.
