Dichoptic Color Difference Threshold Decreases as Brightness Increases

Lustre perception is an important visual ability, but estimating the strength of perceived lustre is a computational challenge for both human and machine vision. We studied the characteristics of binocular lustre perception using the Dichoptic Color Difference Threshold (DCDT). The quantitative relationship between binocular lustre perception and color direction, color difference, and brightness was measured, and the quadratic logarithmic function model of lustre perception and brightness factors was fitted. The experiments and data analysis in this paper shows that brightness has a significant impact on lustre perception, and the research results can provide strong support for lustre reproduction in 3D system design.
