Passive Polarimetric Imagery-Based Material Classification Robust to Illumination Source Position and Viewpoint.

Polarization, a property of light that conveys information about the transverse electric field orientation, complements other attributes of electromagnetic radiation such as intensity and frequency. Using multiple passive polarimetric images, we develop an iterative, model-based approach to estimate the complex index of refraction and apply it to target classification. [ABSTRACT FROM AUTHOR]
