Imaging through scattering media such as fog, clouds, and rain is a challenging problem because light is scattered to the detector from unwanted contaminants in the scene. A number of techniques have been proposed to remove the effect of multiple scattering events on detected signals by placing constraints of various forms that couple properties of the active illumination source to the optical detector. These constraints come in the form of polarization-based, spatial frequency-based, geometric-based, and temporal-based. In the past most of these techniques have been used independently. In this proposal we examine the utility of combining these techniques together. We analyze the performance benefits of each technique and how they are used in combination. The goal is to come up with the best combination of optical domain constraints that have the strongest ability to filter out uncontaminated signals that have been obscured by excessive scattering events.
