In this paper we investigate the transmission rate control of video compression parameters based on the Fourier transform. The application of the two-dimensional second derivative in the problems of image enhancement. The approach is to choose a discrete formulation of the second derivative and the subsequent construction of the filter mask based on this formulation. Studied the use of isotropic filter, the response does not depend on the direction of inhomogeneities on the processed image. The Dirichlet problem for the Poisson equation.
