Polarization provides more detailed description of the light than its power. For this reason, polarized images contain more information than conventional images. It contributes finding of additional solutions for various problems such as object detection, classification, orientation angle detection of objects and acquisition of 3D shapes of objects in the computer vision. In order to obtain linearly polarized images and to determine the linear polarization parameterization of the light by Stokes parameters, it is sufficient to take three linearly polarized images with three different polarizer angles which are 0 degrees, 45 degrees and 90 degrees. In this paper, after a description of polarization parametrization, it has been shown that semi-reflections occurring on transparent or semi-transparent surfaces can be separated by independent components analysis. Experimental work has been done and discussed.
