Nonlinear images processing based on a changing of distributions at parametric and nonparametric stochastic estimation

Nonlinear image processing approaches based on both nonparametric and parametric principles were developed. A new method of nonlinear function determination on the basis of solving a nonlinear equation has been created when this equation was written by cumulative distribution functions of the random variable. The efficiency of the proposed approach was proved with examples of both quality increase of low contrast images with various natures and denoising of radar images at their homomorphic transform.
