Abstract
The authors propose a hierarchical motion estimation algorithm in which the sum of the absolute difference in the Hadamard transform domain is used as its matching measure. The computational complexity of this algorithm was reduced to ~5.6% while the image degradation of its reconstructed image quality was <0.1 dB on average, compared with that of the full search in the pixel domain
