Spatial Information Content Analysis of Wiener Spectra from Polarized Waterwave Imagery
Abstract
This study proposes to analyze the correlation sensitivity of spatial Wiener spectra derived from polarized (Stokes' parameter) imagery of both synthetic and measured waterwave scenes. The intent of this study is to evaluate the utility of polarized imagery in the extraction of spatial information content (to include texture) from scenes containing waterwaves, one of many spatially correlated natural features that can be described by Wiener spectra. This study will first enhance an existing simulation model to support the comparison of the spatial performance of an imaging system through the creation of synthetic polarized images of waterwave scenes and their spatial spectra. Second, this model will be tailored to a specific imaging system: differentially polarized 4-lens 35-mm photography. Third, a parametric exploration of the model will be used to predict the polarized imaging conditions that optimize spatial information content. Fourth, a polarized 4-lens camera system will collect representative imagery containing waterwave scenes under natural conditions. Finally, the synthetic and measured polarized image spectra will be analyzed and compared in order to validate the simulation model, calibrate the imaging system, and ultimately provide the basis for the utility evaluation.
