Fast motion estimation with spatial transformation
K.T. Tan, I.N. Goh, M. Ghanbari · Electronics Letters · 1994
A fast search method for motion estimation with spatial transformations is introduced. While the fast method reduces the number of transformation mappings with a displacement of ±8 pixel/frame from about 7 × 109 to 486, its peak-to-peak signal to motion-compensated noise ratio is, on the average, 3 dB better than that of the conventional full-search block-matching algorithm.
