A system for transform vector coding of images
Remigiusz Jan Rak · 2002
The author describes a full development system for analysis of selected transform vector quantization algorithms for black and white image coding. The software has been developed under the Windows environment. The system is quite open and can be freely 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 area of vector quantization it is equipped with several different structures of algorithms for codebook design. It also includes two procedures for implementing companding techniques. It has the tools for determining the quality of implemented algorithms and achieved level of data compression. A part of the JPEG standard has been used as an origin. The developed system is destined for both research and development and university laboratories.
