Question of the effectiveness of the appearance embedding in Scaffold-GS.

[LZleejean]

Great work.
Could you provide some results for the effectiveness of the appearance embedding. When I eable it.

[Kerui Ren]

The second example in the viewer (https://drive.google.com/file/d/1R53SD7oE-56-PWKjRhHdsnQxNSJyFvPw/view?usp=sharing) is our result of one of training scenes in IMW 2020 (https://www.cs.ubc.ca/research/image-matching-challenge/2020/leaderboard/). You can adjust the appearance embedding to get the effect of day or night. You can also test the reconstruction effect on other scenes in the dataset or take a series of images with different exposures.

Where I can adjust the appearance embedding?

[Tao Lu]

It can be adjusted by feeding the apearance_dim argument, like

Scaffold-GS/train_mip360.sh

Line 5 in 971b681

 appearance_dim=0 

, where 0 denotes not using it, other number like 32 denotes a 32-channel appearance embedding.

Thank you so much, wolud you mind to explain me more about appearance embedding and its number or tell me where I can read about it.

More about it can be found in "NeRF in the wild"(https://arxiv.org/abs/2008.02268).
