...We remark that while most of them were downloaded from the Internet available to the public [7], [31], [32], seven HDR images in the group-2 image database are derived from real scenes corresponding to the actual measured luminance....

...Later, Akyuz and Reinhard adopted the normalized log-average luminance of an HDR image to approximate the key value (ky ) of the scene [31] [32]....

...[21] conducted a subjective experiment using 240 images obtained by tonemapping 20 HDR images with a display adaptive tone-mapping algorithm and compressing them using different profiles of the JPEG XT [23] compression algorithm....

...In other cases, such as [17], metrics have been tested on a single type of distortion only (specifically JPEG-XT compression), thus it is desirable to extend those conclusions to more realistic and variegate conditions....
[...]
...We also confirm the findings in previous work [17, 59] that legacy LDR image quality metrics have good prediction and discrimination performance, provided that a proper transformation such as PU encoding is done beforehand....
[...]
...The capability of both kinds of fidelity metrics to predict viewers’ mean opinion scores (MOS) has been assessed in a number of recent subjective studies using compressed HDR pictures [17, 37, 39, 59]....
