2019 arXiv   pre-print
A challenging data set namely the Zurich Raw-to-RGB data set (ZRR) has been released in the AIM 2019 raw-to-RGB mapping challenge.  ...  We exploit a two-stage U-Net architecture and also introduce a loss function that is less variant to alignment and more sensitive to color differences.  ...  Figure 1 shows our two-stage U-Net based network, called W-Net, for raw-to-RGB mapping.  ...
