In the figures below, we show input sRGB image, original RAW vs. estimated RAW using our method (Eq.11, f, T&h) or using the conventional model (Eq. 4, f, T only), and error maps using our method / the conventional method.(The white points on the difference maps indicate pixels with a value of 255 in any of the channels which are impossible to linearize.)
