Color Gamma Correction: where is gamma?

Hello,

I am trying to use the nppiGamma* functions documented in:

https://docs.nvidia.com/cuda/npp/group__image__color__gamma__correction.html#details

None of these functions take a gamma parameter. How is the gamma set? Is there a global lookup table somewhere? I could not find anything.

Thanks

These functions should be similar to the ipp functions/method:

If you do a google search on “ipp gamma correction” you will find other links such as those describing the color spaces, etc.

Ok, thanks!
