Abstract
In this paper a subjective test in which participants
evaluate the quality of JPEG-XT compressed HDR images is
presented. Results show that for the selected test images and
display, the subjective quality reached its saturation point starting
around 3bpp. Objective evaluations are obtained by applying a
model of the display and providing the modeled images to three
objective metrics dedicated to HDR content. Objective grades
are compared with subjective data both in physical domain
and using a gamma correction to approximate perceptually
uniform luminance coding. The MRSE metric obtains the best
performance with the limit that it does not capture the quality
saturation. The usage of the gamma correction prior to applying
metrics depends on the characteristics of each objective metric.
