The 'filter_R' of lumopt

In the Greyscale part, I can't understand what is the 'top hat convolution'.

After consulting some materials, I also saw some materials mentioning low-pass filters. Is'filter_R' the radius of the low-pass filter? Is it the same thing?

Thank you all and look forward to your reply😁😁
