Multi-valued Images and Their Separation

Abstract. Consider scenes deteriorated by reflections off a semireflecting medium (e.g., a glass window) that lies between the observer and an object. We present two approaches to recover the superimposed scenes. The first one is based on a focus cue, and can be generalized to volumetric imaging with multiple layers. The second method, based on a polarization cue, can automatically label the reconstructed scenes as reflected/transmitted. It is also demonstrated how to blindly determine the imaging PSF or the orientation of the invisible (semi-reflecting) surface in space in such situations.
