Observer metamerism in commercial displays.

Two uniform patches presented on two displays under identical viewing conditions can appear as the same color to one observer but as mismatched colors to another observer. This phenomenon, called observer metamerism (OM), occurs due to individual differences in color matching functions. To avoid its potentially adverse impacts in display calibration and characterization, it is desirable to have a predictive model of OM.

Designing pictorial stimuli for perceptual experiments.

The effects of design decisions in the development of systems that generate images for human consumption, such as cameras and displays, are often evaluated using real-world images. However, human observers can react differently to complex pictorial stimuli over the course of a lengthy experiment. This study was conducted to develop understanding of the optimal design of pictorial stimuli for effective and efficient perceptual experiments.
