Set partitioning in hierarchical trees

From Wikipedia, the free encyclopedia

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.
