WebThe key concept of this tone mapping method (Lightness Perception in Tone Reproduction[8]) is a decomposition of an HDR image into areas (frameworks) of consistent illumination and the local calculation of the lightness values. The net lightness of an image is calculated by merging of the frameworks proportionally to their strength. high speed efm providers
