Clustering and colour preview of polarization-encoded images

In the framework of Stokes parameters imaging, polarization-encoded images have four channels which make physical interpretation of such multidimensional structures hard to grasp at once. Furthermore, the information content is intricately combined in the parameters channels which involve the need for a proper tool that allows the analysis and understanding of polarization-encoded images. In this paper we address the problem of analyzing polarization encoded images and explore the potential of this information for classification issues and propose ad hoc colour display as an aid to the interpretation of physical properties content. We propose a novel mapping between the Stokes space and a parametric HSV colour space.
