Set partitioning in hierarchical trees (SPIHT)
is an
image
An image is a visual representation of something. It can be two-dimensional, three-dimensional, or somehow otherwise feed into the visual system to convey information. An image can be an artifact, such as a photograph or other two-dimensiona ...
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.
General description
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.
