Studies of the Effect of Image Degradation and Recombination on Visual Perception

摘要

In the first year of this grant progress was made on two major series ofexperiments. In the first, we examined the effect of noise, brightness, contrast, and geometrical artifacts on a detection task simulating enhanced night vision devices in a series of 10 experiments. An article has been submitted based on this study. In the second, we explored the effects of noise, Fourier filtering, reduced acuity (by means of blocking) and combinations thereof in a discrimination task. Ten experiments also have been carried out in this series and are now been analyzed and a publication is being prepared.
