contrast kernel

The problem of no-reference measurement of generalized (full integral) contrast of complex (multi-element) monochrome images for objective assessment of their quality is considered in this paper. Different approaches to the quantitative assessment of the generalized contrast of a complex monochrome image on the basis of an analysis of the contrast values of image elements relative to a preset level of adaptation are considered. The task of measuring the contrast of image elements (objects and background) for a preset adaptation level is solved.

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.
