About calculating mask

[ShaofengZou]

Hey,

I am curious about the real implement of the calculation of the mask.

In the supplemental, the mask is the product of two binary masks:

The first is based on the previous paper, and the other is based on the warping residue.

However, i find three mask in the code: exclusive_mask1*Mask1*warped1.

So i want to know what is the difference between the mask calculated in collision_mask folder and the original method in model-blind video denoising via frame-to-frame training.
