It analyzes the optical flow that results from perspective distortions during motions of the observer and tries to use this information for computing the correct image warping. If this fails due to an unreliable optical flow, an accurate -but slower and visiblestructured light projection is automatically triggered. Together with an appropriate radiometric compensation, view-dependent content can be projected onto arbitrary everyday surfaces. An implementation mainly on the GPU ensures fast frame rates.}, keywords = {4(2007)6 4.2007 Correction DiPP Digital_Peer_Publishing_Initiative GI_ARVR_2006 GPU Geometric_Calibration JVRB Journal_of_Virtual_Reality_and_Broadcasting Open_Access Peer_Reviewed Perspective_Distortion Projections Surfaces [ZLB07] } }
