Studies of the Effect of Image Degradation and Recombination.
Abstract
During the three year period of this grant, progress was made on two major series of experiments and some minor themes. In the first major one, we examined the effect of noise, brightness, contrast, and geometrical artifacts on a detection task simulating enhanced night vision devices. In the second, we explored the effects of noise, Fourier filtering, reduced acuity (by means of blocking) and combinations thereof on the discrimination and recognition of aircraft silhouettes and faces. The major empirical contribution of this work was the parametric exploration of a number of the key variables in visual perception. The major theoretical contribution was the proof that the Fourier components of an image were, at best, only a partial determinant of our perceptual response.
