Abstract

Recursive pyramidal image representation in image coding algorithms through the use of the pyramid structure, and recursive two-dimensional scannings are introduced. Two approaches to the decorrelation of the picture elements in such a data structure are considered. Properties of different two-dimensional scannings as well as statistical properties of the recursive pyramid and their use for the development of image coding algorithms are shown. Experimental results demonstrating the achieved compression ratio and distortions are provided.
