Hi, thanks for your work and datasets.

I am a little confused because I cannot reproduce the HDR results reported in your paper.

By using your code, the reconstructed HDR PSNR results on the synthetic dataset is

But the results reported in the paper is

Could you please help me explain this? Thanks.

it is almost 10 dB lower than the results reported in your paper

你好，在计算HDR图像的PSNR的时候，我们用了论文公式14进行tone mapping，再计算PSNR。另外，用Phontomatix打开这些HDR图像是否正常？你可以用Phontomatix里面的tone mapping算法，导出LDR图像看看。

进行了的，不进行根本测不了。你提供的代码中没有 HDR 图片测试的部分，我是根据你文中的描述，自己写了一段测试，发现PSNR远没有文中报的那么高

我更新了hdr的测试代码，你可以试试。

感谢，如果可以的话，能share一下所有scene上训好的weights吗？这样子其他人想和你对比，直接test就行，不用自己 train 一遍了。方便提升这篇文章的影响力和引用量的
