QccPack—Quantization, Compression, and Coding Library

About QccPack

QccPack provides an open-source collection of library routines and utility programs for quantization, compression, and coding of data. QccPack has been written to provide very flexible and general implementations of procedures commonly used in coding and compression applications. QccPack is intended for use in the development of prototypes of coding and compression systems, and in academic research. QccPack includes routines for entropy coding, scalar quantization, vector quantization, and wavelet transforms. Additonally, an open-source implementation of SPIHT is available as an optional module.


A large portion of the QccPack library was written while James E. Fowler held a postdoctoral position at Laboratoire I3S, Université de Nice-Sophia Antipolis, Sophia Antipolis, France, and was based upon work supported by the National Science Foundation under Grant No. INT-9600260. Subsequent support was provided by the National Science Foundation under Grant Nos. ACI-9982344 and CCR-0310864.
