HYBRID ORTHOGONAL APPROXIMATION OF NON-SQUARE AREAS
Jaroslav Polec, T. Karlubikova, Anton Březina · Kluwer Academic Publishers eBooks · 2006
The work deals with possibilities of approximation of non-square areas using combined discrete orthogonal transforms (DOT), where image data are represented using less spectral coefficients than in the case of single transform approach. The work is based on an assumption that properly chosen orthogonal transforms complete each other in the process of image approximation.
