Abstract
In video coding, affine motion models combined with a quadtree decomposition have often been suggested as an extension to the mostly used translational models combined with a blockwise decomposition. What is missing so far is a thorough analysis to judge the tradeoff between using more complex motion models or more elaborate decomposition methods in terms of data compression and information loss. In this paper, we compare different polynomial motion models with a quadtree decomposition concerning motion model complexity and granularity of decomposition. We provide a statistical evaluation based on optical flow databases to quantitatively find a tradeoff between bitrate and reconstruction error.
