How to make the luminance of HDR datasets in the same scale? #14

Closed Mrwjm closed 2 years ago

The luminance of HDR panoramas in the Laval datasets maybe in the different scales.Did you make the HDR panoramas in the same scale? How to do that?

For the processing of training data in distribution-based representation, I don't adjust the luminance scale.

For the visualization of illumination map, the luminance intensity should be scaled through tone-mapping, please check here: https://github.com/fnzhan/Illumination-Estimation/blob/d93bff75edf43c42277182cb0a53509d66d76bad/RegressionNetwork/util.py#L29
