Abstract:

A means of quantifying the cluttering effects of symbols is needed to evaluate the impact of displaying an increasing volume of information on aviation displays such as head-up displays. Human visual perception has been successfully modeled by algorithms that process an image through a bank of visual filters for a range of spatial frequencies and orientations. The model proposed here derives a vector of "feature density" values from these filtered images where each value represents the degree to which the image contains a particular spatial frequency and orientation. Differences in these feature densities between a target and a context is used to calculate the degree the target is salient relative to the context.
