Visualization Techniques for Four-Strokes Parameter Polarization

Abstract : The human visual system can barely detect polarized light. This paper outlines a methodology for displaying and visualizing polarization profiles of natural, daylight scenes. A pseudo color scenes. based on the Poincare sphere, is developed for encoding the various polarization parameters in a scene. A mathematical model of the polarization state of skylight is given. A pictorial representation of the polarization state of the sky, using the Poincare colorization methodology, is presented. Using the colorization methodology, a visual correlation is given between the polarization states of light reflected from a target and the solar illumination producing it.
