QccPack: an open-source software library for quantization, compression, and coding

Abstract

Summary form only given. We describe the QccPack software package, an open-source collection of library routines and utility programs for quantization, compression, and coding of data. QccPack is written to expedite data compression research and development by providing general and reliable implementations of common compression techniques. Functionality of the current release includes entropy coding, scalar quantization, vector quantization, adaptive vector quantization, wavelet transforms and subband coding, error-correcting codes, image processing support, and general vector-mathematics, matrix-mathematics, file-I/O, and error-message routines. All QccPack functionality is accessible via library calls; additionally, many utility programs provide command-line access. Although primary development efforts have concentrated on the Red Hat Linux i386 platform, it should be a straightforward procedure to build QccPack on other varieties of Linux as well as non-Linux UNIX-based systems.
