Abstract:
Gloss perception, a crucial visual ability, poses computational challenges for human and machine vision when estimating surface glossiness. The Dichoptic Color Difference Threshold (DCDT) is a quantitative metric to assess the minimal discernible color variation in binocular luster perception. In this study, we investigated the relationship between binocular luster and color hue, color difference, and luminance factors by quantifying and measuring DCDTs under binocular equivalent luminance conditions. Additionally, we fitted a quadratic logarithmic function model to describe the association between binocular luster and luminance factors. The experiments and data analysis presented in this article demonstrate that luminance significantly influences binocular luster. These research findings provide robust support for luster reproduction in three-dimensional system design.
