A system for transform vector coding of images

There is described a full development system for analysis of selected transform vector quantization algorithms for black & white image coding. The software has been developed under the Windows environment. The system is quite open and can be fi eely expanded and modified, Up to this time it has been equipped with two basic transform algorithms: Discrete Fourier Transform (DFT) and Discrete Cosine Transform (DCT). In the al ea of vector quantization it is equipped with several different structures of algorithms for codebook design, It also includes two procedures for implementing companding technique. It certainly has the tools for determining the quality of implemented algorithms and achieved level of data compression. A Dart of JPEG standard has been used as an origin. The developed system is destined for both research & development and university laboratories.
