Adaptive Enhancement of Monochrome Images with Low Contrast and Non-uniform Illumination

The problem of adaptive enhancement for complex images with low contrast and non-uniform illumination is considered. The histogram-based method of image contrast enhancement in automatic mode on the basis of the estimations of parameters of distribution of brightness values at the boundaries of objects and background for the various known definitions of contrast kernels is proposed. The research of the effectiveness of the proposed and well-known methods of image contrast enhancement is carried out using the known no-reference metrics of generalized contrast of image.
