Possibilities of Using Several Discrete Transforms for the Video Compression

Abstract

This paper treats of compression of digital video signals and the main aim is to probe the possibility of using several discrete transforms besides well-known discrete cosine transform (DCT). Mathematical description of these transforms is presented in the article. DCT and other orthogonal transforms are described here. Matrix notation of computation of two-dimensional transform is also presented. The comparison of the results obtained by application of the transforms on pictures is introduced.
