SPIHT-NC: Network-Conscious Zerotree Encoding

open access: yes, 2000
Wavelet zerotree encoding has been proven to be an efficient way of compressing still images. Two well-known zerotree encoding algorithms, Embedded Zerotree Encoding (EZW) and Set Partitioning in Hierarchical Trees (SPIHT), provide excellent ...

Implementacija SPIHT

open access: yes
In this thesis, first, the Haar transform is presented. Then, the basic concepts and data structures necessary for understanding the SPIHT algorithm are explained. Pseudocode implementations of encoding and decoding are presented. Their functioning is illustrated with an example. The algorithm is implemented and tested on different images.

Embedded Coding of Astronomical Images

open access: yesActa Polytechnica, 2006
Recursive partitioning of significant wavelet sub-bands (RPSWS) is an embedded rate scalable wavelet-based image coding algorithm. The RPSWS coder produces a fully embedded bit stream and encodes the image to exactly the desired bit rate (precise rate ...

An Embedded Wavelet Video Coder Using Three-Dimensional Set Partitioning in Hierarchical Trees (SPIHT)

open access: yes, 1997
The SPIHT (set partitioning in hierarchical trees) algorithm by Said and Pearlman is known to have produced some of the best results in still image coding. It is a fully embeded wavelet coding algorithm with precise rate control and low complexity.
