🧑‍🎨 Create Your Own Video Storyboard! 🧑‍🎨

Due to LE3D's capability for real-time rendering, once the reconstruction results are obtained, we can perform real-time rendering on them. Additionally, since the reconstruction results from LE3D are in the HDR color space, it allows for exposure variation as well as local and global tone-mapping operations. Our interactive viewer enables users to edit the scene in real-time, and it will provide functionality for creating video storyboards using keyframes in the future.

🆚 Comparison Between LE3D, RawNeRF and RawGS*

RawGS* denotes a 3DGS trained with RawNeRF's weighted loss and multi-exposure strategy.

Comparison with RawNeRF

Comparison with RawGS

Compared to RawNeRF (left), LE3D can perform real-time rendering at 2K resolution, and as a result, it can also conduct nearly real-time postprocessing (our interactive viewer). In comparison with RawGS, LE3D possesses superior capabilities in scene structure optimization, and additionally, it has fewer residual floaters in the air.

🎑 Denoising Ability 🌃

LE3D has a natural noise resistance similar to RawNeRF, which is attributed to the noise2noise assumption and the fact that the noise is entirely located on the camera plane, rather than being distributed in space.
