image quality assessment

Generalized description of contrast of image elements

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.
