Dataset Construction in BID Model's Task II.A

[Adele0108]

Thank you for your excellent work on the BID model and for making it publicly available. I have a few questions about the dataset construction in Task II.A:

(1) The clean CityScape training set contains 2975 images, but the provided masks have different counts (rain streaks: 1620; raindrops: 3500; snow: 3500). Could you clarify how these masks are applied given the count mismatch?

(2) Some masks don't match CityScape's standard 1024×512 resolution. How are these different-sized masks properly aligned with the base images?

(3) Would it be possible to release the complete multi-weather dataset to facilitate reproducibility?

(4) Currently, raina_dataset.py doesn't support testing individual weather cases separately. Could you please provide the dataset code for testing individual weather cases separately?

I greatly appreciate your time and consideration of these questions. Looking forward to your reply!
