Image compression algorithm
Set partitioning in hierarchical trees
(
SPIHT
)
[1]
is an
image
compression algorithm
that exploits the inherent similarities across the subbands in a
wavelet decomposition
of
an image
. The algorithm was developed by Brazilian engineer Amir Said with William A. Pearlman in 1996.

The algorithm
