Abstract

In this work the well known wavelet/subband decomposition algorithm (3-D case) widely used in picture and video coding is parallelized using PVM and MPI as well as with data parallel language extensions. The approaches try to take advantage of the possibilities the respective programming interfaces offer. Experimental results are conducted on an SGI POWERChallenge GR and an SGI Origin 2000. These results show a good comparison of the programming approaches as well as the programming interfaces in a practical environment.
