Understanding some steps in the paper.

[jiangyijin]

Thank you very much for your work.
I have a few areas in your paper that I did not fully understand. Could you please provide me with some assistance?

1. Did you first perform low-resolution optimization and then proceed to high-resolution optimization to achieve a step-by-step increase in resolution and obtain more detailed reconstruction?
2. Did you use CROSS-RAY DENSIFICATION and MULTI-VIEW AUGMENTED DENSIFICATION in each optimization process at different resolutions?
3. When using CROSS-INTRINSIC GUIDANCE to identify the regions that require optimization, since you have multiple views, how did you determine which image(s) were good and then increase the number of Gaussian balls in that area based on those image(s)?
4. Were all of the optimization steps you mentioned performed using multiple views?
