Wavelet packet best basis selection on moderate parallel MIMD architectures

Wavelet packet best basis selection has become a popular method in image compression. This paper introduces a subband based parallelization which overcomes most of the difficulties of a straightforward parallel version of the sequential algorithm.

Popis
Shrnutí:Wavelet packet best basis selection has become a popular method in image compression. This paper introduces a subband based parallelization which overcomes most of the difficulties of a straightforward parallel version of the sequential algorithm. Beside the higher efficiency the algorithm is easier to implement than its classical version.
