The most widely used EOTF for HDR content is the 12-bit perceptual quantizer (PQ) curve [10], also known as the ST. 2084 standard that covers 0 to 10,000 nits.

We use the term perceptual coding to signify the matching of the quantizer to the human auditory or visual system, with the goal of either minimizing perceived ...
