Adapt an image, which may have a high dynamic range, for presentation using a low dynamic range. This operator attenuates the magnitudes of local image gradients, producing luminance within the range 0.0-1.0. This tonemapping approach was originally presented by Raanan Fattal, in the 2002 SIGGRAPH paper: Gradient Domain High Dynamic Range Compression.
Moldatu irudi bat, barruti dinamiko handia eduki dezakeena, barruti dinamiko baxuko aurkezpen batean erabiltzeko. Eragile honek irudi lokalaren gradienteen magnitudeak ahultzen ditu, luminantzia 0.0-1.0 barrutian sortuz.
