Bandpass Spatial Filtering and Information Content.

Abstract

Gaussian weighted, bandpass spatial filters were applied to pictures of tactical fighter aircraft through two dimensional, Fourier Transform processing. Subjects were required to rate image interpretability and report their confidence. No significant difference was found between aircraft for interpretability or confidence. Filter center frequency was found to be highly significant (p < 0.01), and the difference between subjects was found to be significant (p < 0.05) with respect to interpretability. The main effect of filters was found to be significant (p < 0.05) for the dependent measure of confidence. A predictor equation was developed though linear regression to relate filter center frequency and image interpretability (r-sq = 0.5623).
