Separating virtual and real objects using independent component analysis

We often see reflection phenomenon in our life. For example, through window glass, we can see real objects, but reflection causes virtual objects to a ppear in front of the glass. Thus, it is sometimes difficult to recognize t he real objects. Some works have been proposed to separate these real and v irtual objects using an optical property called polarization. However, they have a restriction on one assumption: the angle of incidence. In this pape r, we overcome this difficulty using independent component analysis (ICA). We show the efficiency of the proposed method, by experimental results.
