Vision through semi-reflecting media: polarization analysis (1999) [3 citations — 3 self]
Abstract:
We present an approach to recover scenes deteriorated by reflections off a semireflecting medium. The approach is based on imaging through a polarizer at two different orientations. We analyze the image formation process taking into account changes in the reflection and polarization properties due to internal reflections within the medium. Reconstruction by inverting this process requires the estimation of the incidence angle (the inclination of the transparent medium). This angle is estimated by seeking the value which leads to decorrelation of the estimated scenes that are automatically and uniquely labeled as reflected/transmitted. 1 The situation in which several (typically two) linearly superimposed contributions exist is often encountered in real-world scenes. For example [1, 2, 3], looking out a car (or room) window, we see both the outside world (termed real object [2, 4]), and a semi-reflection of the objects inside, termed virtual objects. The separation of unrelated contributions to a scene is important for its understanding and analysis. In fact, the mere detection of such a
