Image range processing in the experiment stage about hdr-expandnet HOT 1 CLOSED

Hi there,

Thank you for your interest. The images are scaled in the same way for all methods, including ExpandNet, as mentioned in the paper.

1. If the scaling is built-in for a particular method (i.e. max luminance is needed for the EO):

For the display-referred scaling, the maximum luminance of the display is given as a parameter to the EO algorithm.
For the scene-referred (original HDR range) scaling, the default value of the algorithm is used and then scaled linearly to match the original HDR.

2. If the scaling is not built in, then the scaling is done in the same way as for ExpandNet.

The rest is the same as described in the paper (e.g. scale the 0.1 and 99.9 percentiles to match the corresponding percentiles in the target range).

Hope this helps,
Demetris
