mask[mask > XX] = 255, mask[mask <=XX] = 0, is the value of XX an experience value? Does the XX threshold need to be set differently for different graphs?

I think it is because the range of mask is 0-8, here it is set to 4, taking the middle value. And, according to the distribution law of the samples, the threshold can be adjusted appropriately, such as when there are too few positive samples, it can be set to 2.4 or something like that.
