[POSTER] TOWARD MOBILE DIMINISHED REALITY

We present a diminished reality application running live on consumer mobile devices. In our pre-observation-based approach; the clean 3D scene; free of undesired objects; is scanned beforehand and reconstructed as a high resolution textured 3D model. At runtime; objects added in a region of interest are efficiently removed by projecting the previously captured background. Differences of illumination conditions between scan time and run-time are compensated to obtain seamless results. The proposed approach requires no segmentation or manual input other than the definition of the 3D region of interest to be diminished; and is not based on any particular assumption on the background geometry. We show the potential of our approach by processing a variety of challenging unknown 3D scenes including textured backgrounds; dynamic illumination conditions and foreground objects partially occluding the diminished region. We provide details on our compute shader implementation to make as easy as possible the reimplementation by the community.
