Abstract

The focus of the current study is the comparison of multiple contrast metrics... The images of pedestrians from a previous nighttime research study were used for analysis. The pedestrians were clothed in both denim and black-colored clothing under both high-pressure sodium (HPS) and metal halide (MH) overhead lights, and images were captured at multiple distances. --executive summary.
