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.
