  The principle of the polarimetric imaging method called APSCI (Adapted
Polarization State Contrast Imaging) is to maximize the polarimetric contrast
between an object and its background using specific polarization states of
illumination and detection. We perform here a comparative study of the APSCI
method with existing Classical Mueller Imaging(CMI) associated with polar
decomposition in the presence of fully and partially polarized circular
Gaussian speckle. The results show a noticeable increase of the Bhattacharyya
distance used as our contrast parameter for the APSCI method, especially when
the object and background exhibit several polarimetric properties
simultaneously.
