Abstract
The problem of image quality assessment in the transmission and processing of video data in information and telecommunication systems is considered. The task of no-reference measurement of contrast of two image elements (objects and background) for complex (multi-element) images is solved. A new method of contrast measurement of elements of complex images on the basis of analytical assessments of contrast of appropriate elements on initial (primary) and on inverse (negative) images is proposed. А generalized description of image elements contrast for different definition of contrast kernels is suggested. The new definitions of a weighted and relative contrast of image elements are proposed. The research of known and proposed definitions of a weighted and relative contrast to evaluate the efficiency of measuring (of quantitative assessment) of contrast of image elements was carried out.
