Abstract:
The article provides a comparative analysis of the effectiveness of two-dimensional discrete orthogonal transforms (DOT) for image compression. Several evolvements of two-dimensional fields are shown that provide low correlation of transformants when applying one-dimensional DOTs to them. The article also explores the possibility of using one-dimensional DOTs defined on such evolvements as an alternative to two-dimensional ones.

Keywords:
image compression, discrete orthogonal transform, DOT, two-dimensional field.
