Analysis of the effectiveness of unitary transformations in image compression algorithms

At the present stage, the development of information systems storage, processing and transmission of multimedia data is impossible without the use of compression techniques, which require a correct comparison on the basis of analysis of the effectiveness of the fundamental unitary transformations. A statistical analysis of the effectiveness of the fundamental unitary transformations, which are used in image compression algorithms. It is noted that one of the most effective transformation is the Karhunen-Loeve transformation, which has the property of full de-correlation coefficients. However, in the existing image compression formats used by the most similar characteristics with further conversion of the quantization coefficients.
