摘要

Our visual environment contains both luminance and color (chromatic) information. Understanding the role that each plays in our visual perception of natural scenes is a continuing topic of investigation. In this study, we explore the role that color cues play in a specific task: edge classification. We conducted a psychophysical experiment that required subjects to classify edges as shadow or other , depending on whether or not the images contained color information. We found edge classification performance to be superior for the color compared to grayscale images. We also defined machine observers sensitive to simple image properties and found that they too classified the edges better with color information. Our results show that color acts as a cue for edge classification in images of natural scenes.
