Would you please share the method to extract the mask from the image pair (shadow and shadow-free)?

It's a great job!
As you mentioned for the SRD masks, "Hi, we also use a simple rule to extract the mask from the image pair."

Would you please share the method to extract the mask from the image pair (shadow and shadow-free)?

Hi, thanks for your attention.

I just transform the images in the log space and threshold the difference.

The original scripts for mask extraction are missing, however, I will try my best to release a similar one.

Thanks a lot!
Looking forward for the extraction script.

Hi Vinthony,

Have you been able to recreate the script for mask extraction?
Kind regards

Hello, I would like to ask you what is the threshold when converting the image to a binary image of shadow mask after getting the difference between the shadow image and the non-shadow image after converting the image to log space?
