  abstract = "In this paper we present a hybrid technique for correcting
              distortions that appear when projecting images
              onto geometrically complex, colored and textured surfaces.
              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."
