@Filoppi Hey! Thanks. I tend to agree with you. But I will cancel this PR because the sum of your coefficients is > 1.0. I will fix coefficients in my local version and update GitHub early next week. Coefficients will be 0.2126, 0.7152, 0.0722
.
This is a common mistake, as google research often come up with the BT.601 values instead of ~"0.2126729 0.7151522 0.072175".
I'm assuming the denoiser isn't using BT.601 internally, but I highly doubt it is :).
