In this paper we propose a ratio that help determine sub-areas of spatial frequencies at a selected unitary transformation, we introduce the concepts of parts and a shares of image energy in a given subarea of spatial frequencies for the chosen system of orthogonal basis functions. In the paper we describe a system of orthogonal basis functions for different unitary transformations, we propose on the basis of a separate unitary transformation calculation procedure of subinterval matrices, allowing to analyze the image properties in different subareas of spatial frequencies.
