SWAGS: Sampling Windows Adaptively for Dynamic 3D Gaussian Splatting

no code implementations20 Dec 2023 Richard Shaw, Jifei Song, Arthur Moreau, Michal Nazarczuk, Sibi Catley-Chandar, Helisa Dhamo, Eduardo Perez-Pellitero

We model the dynamics of a scene using a tunable MLP, which learns the deformation field from a canonical space to a set of 3D Gaussians per frame.

Park

The challenge is composed of two tracks with an emphasis on fidelity and complexity constraints: In Track 1, participants are asked to optimize objective fidelity scores while imposing a low-complexity constraint (i. e. solutions can not exceed a given number of operations).

HDR Reconstruction from Bracketed Exposures and Events

no code implementations28 Mar 2022 Richard Shaw, Sibi Catley-Chandar, Ales Leonardis, Eduardo Perez-Pellitero

Our proposed approach surpasses SoTA multi-frame HDR reconstruction methods using synthetic and real events, with a 2dB and 1dB improvement in PSNR-L and PSNR-mu on the HdM HDR dataset, respectively.

Self-supervised HDR Imaging from Motion and Exposure Cues

no code implementations23 Mar 2022 Michal Nazarczuk, Sibi Catley-Chandar, Ales Leonardis, Eduardo Pérez Pellitero

Recent High Dynamic Range (HDR) techniques extend the capabilities of current cameras where scenes with a wide range of illumination can not be accurately captured with a single low-dynamic-range (LDR) image.

FlexHDR: Modelling Alignment and Exposure Uncertainties for Flexible HDR Imaging

no code implementations7 Jan 2022 Sibi Catley-Chandar, Thomas Tanay, Lucas Vandroux, Aleš Leonardis, Gregory Slabaugh, Eduardo Pérez-Pellitero

We introduce a strategy that learns to jointly align and assess the alignment and exposure reliability using an HDR-aware, uncertainty-driven attention map that robustly merges the frames into a single high quality HDR image.
