Can saliency guidance be used in the 2nd LID challenge Track1?

The 1st Learning from Imperfect Data Challenge
1

Hi, I want to use saliency guidance in my work, but I find that “For training, only the images provided in the training set are permitted” from a description of the challenge.

So is saliency guidance allowed at The 2nd LID Challenge Track1 (Weakly-supervised Semantic Segmentation)?

Thanks.
