Set partitioning in hierarchical trees
From Wikipedia, the free encyclopedia
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.[1]
General description
[edit ]The algorithm codes the most important wavelet transform coefficients first, and transmits the bits so that an increasingly refined copy of the original image can be obtained progressively.
