English title
Lossless Image Compression Using Wavelet Transform
Language
Czech
Abstract

This work focuses on wavelet transform and its use in image compression particularly on a comparation between classical tensor product wavelets and new kind of second generation wavelet also known as red-black wavelet transform. Although brief comparison of EBCOT modifications, color transforms, wavelets and predictors are discussed too. A framework for an evaluation of some current methods is constructed and results across different image groups are presented. In addition, C++ library was created. Proposed lossless compression methods are better then JPEG 2000 and PNG.

Keywords

Lossless image compression, wavelet transform, red-black wavelet transform, image decomposition, color transform, predictor
