About Low-Rank 4D Bilateral Grid

[WuJH2001]

Thanks to the author for this work, I am very confused about why similar objects in the entire scene can be treated with the same edit after 4D bilateral grid CP decomposition, such as the grass in the paper. Why the table won't be changed color

Hi,

I think this is owing to the good properties of the "bilateral" processing, i.e., the color transform for each point is based on two dimensions: its location and values. The table and the grass are not in the same location or value. So they will be processed by different transforms.

Thank you very much！
