Parallel Direct Vector Quantization (VQ) and LBG algorithms <author> <version> <abstract> This package contains programs which implement Direct Vector Quantization, the LBG algorithm for codebook design and Vector Quantizer decoder. The first two are written using the MasPar programming language (MPL). The decoder is written in ANSI C. The programs are written to accomodate a range of Codebook and Vector sizes. In addition to these, there are also programs to convert 2-D signals of specified dimensions into a stream of vectors and vice versa. All the programs assume the image to be 512 x 512 monochrome images stored in the Sunraster format. They would require additional modifications to accomodate images of arbitrary sizes and other raster formats. <description><url>http://sdcd.gsfc.nasa.gov/ESS/exchange/contrib/mathews/VQ.html</url> <reference><url></url> <contact> <keywords>image processing; vector quantization; parallel application library <category>application <publication-date> <environment>MasPar programming language (MPL), C <method> <application> <comments> </urc>
