Abstract :
This paper presents a subjective experiment collecting quality assessment of images displayed on a LCD with local backlight dimming using two methodologies: absolute category ratings and paired-comparison. Some well-known objective quality metrics are then applied to the stimuli and their respective performance are analyzed. The HDR-VDP metric seems to achieve good performance on every source image.
