Spatio-temporal motion estimation for transparency and occlusions
Erhardt Barth, Ingo Stuke, Til Aach, Cícero Mota · 2004
We present a spatio-temporal analysis of motion at occluding boundaries as an extension of previous results for trans- parent motions. We show how these new results generalize alternative approaches derived in the Fourier domain that are limited by assuming straight occlusion boundaries. Furthermore, we derive a novel hierarchical algorithm that can deal with single, multiple-transparent, and occluded motions.
