Resolution enhancement by image fusion for microgrid polarization imagers

Abstract

Microgrid polarization imaging systems inherently suffer from spatial aliasing in addition to the image degrading effects of camera blur and noise. In this paper, microgrid aliasing is reduced by a factor of two and noise is suppressed via a fast image fusion technique borrowed from the study of super resolution. Additionally, a new regularization cost function for microgrid super resolution estimators is proposed. Polarimetric image fusion results are demonstrated with laboratory data.1 2
