7. Advanced7.8.11.2 Illustrating the influence of GLD correctionIllustrating GLD correctionWithout performing GLD correction, we have a linear response1 from black to white. This is shown as a green dashed line in thegraph below, where we the horizontal axis represents the signal strength (0% to 100%) and the vertical axis the intensity.Linear responseIntensitySignal05121024025% 50% 75% 100%Image 7-168GLD: response curveThe following topics give you an overview of the outcome of the GLD corrections done at different levels.GLD correction on Hierarchy level 1When a correction is applied to Hierarchy level 1 (blue line), its main influence is visible on 25% level. The sum of the adjustmentand the linear transition results in a transition as it is presented by the dash-dotted red line in the graph below.AdjustmentLinear responseSumIntensity Adj. valueSignal01.01.50.55121024025% 50% 75% 100%Image 7-169GLD correction on Level 1GLD correction on Hierarchy level 3Following graph illustrates the same correction done on Hierarchy level 3.1. To be fully correct, we will have the gamma response curve instead of a linear response curve. In this explanation, we consider it to be linear however.R59770330 SIM 7QP SERIES 07/10/2013 209
