CCSDS 122.0-B-1

CCSDS 122.0-B-1 is a CCSDS Lossless to Lossy Image compression standard released on November 2005.This CCSDS standard is a discrete wavelet transform (DWT) transform coder followed by a Rice encoder & a Bitplane encoder on the similar lines as Embedded Zerotree Wavelet by Shapiro.

Encoder

It is a 3level 2D-DWT using a biorthogonal 9/7 (LPF/HPF) tap filters, followed by a bit-planeencoder.

The encoder can use either floating point or Integer DWT. Integer DWT is the lossless coding scheme, while thefloating point DWT contributes to the lossy scheme.
