Embedded Coding of Astronomical Images
Acta 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 ...

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.

SPIHT-NC: Network-Conscious Zerotree Encoding
, 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 ...
