  • Abstract
    Set partitioning in hierarchical trees (SPIHT) is a scalar quantiser for images that have undergone subband decomposition by wavelet transform. Reduced bit rates have been achieved by merging the first and second passes of the already efficient SPIHT algorithm. The modification requires neither entropy encoding nor significant increase to the algorithmic complexity.
