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."
