Color and Luminance Interactions in the Visual Perception of Motion and Depth

抄録

Many studies have suggested that color and luminance are separately mediated by different processing streams in the early visual system and that the two information cues play different roles in the perception of motion, depth and shape. One major suggestion in these studies is that luminance information is the main contributor to motion and depth detection. Although color information was not considered as an important cue, recent studies have shown that color signals contribute to the detection of motion and depth as well. To sort out the relative contributions of both information cues and to shed light on the visual mechanism behind motion and depth detection in general, we have investigated how color information is processed in the presence of luminance information.
