MEASURING THE VISUAL COMPLEXITY OF NIGHTTIME ROADWAYS
The research described here concerns the difficulty of interpreting complex nighttime road scenes. Subjectively, sometimes a driver's view of the road ahead is more difficult to interpret or utilize than at other times. Cues to the path ahead may be low-contrast, diffuse, or ambiguous. Additional elements of the scene may complicate the visual information processing problem: concepts such as visual noise, clutter, information load, and complexity have been applied to this issue. This paper describes an effort to measure and model the visual difficulty of the view ahead for the motorist.
