- 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.
