Automatic Enhancement of Low-Contrast Monochrome Images

The problem of images enhancement in automatic mode with an acceptable level of computational costs is considered. The task of adaptive enhancement of integral contrast for complex monochrome images on the basis of their nonlinear statistical non-inertial transformations is considered. The research of the effectiveness of the main histogram-based methods of enhancement of the integral contrast of complex images with low-contrast small-sized objects and non-uniform illumination is carried out. A comparative analysis of the effectiveness of no-reference assessing the generalized contrast of complex images using the histogram-based metrics of integral contrast and on the basis of expert assessments is carried out.
