About CurveNLU

[KKKLeouee]

Different from Zero-DCE that uses different curves for RGB channels, CurveNLU applies the same curve to different channels in the feature domain. Are you fitting all the pixel points with a curve to get the best curve parameters? I don't really understand that CurveNLU applies the same curve to different channels in the feature domain. Could you explain this knowledge? Sorry for any interruptions. thank you
