Abstract

A digital phase manipulation for images processing on the algorithm similar to the optical Foucault knife considers by means of computer modeling method. The images quality preservation at decomposition in Walsh-Hadamard and Haar spectrum was investigated. It is shown, that Foucault knife for the digital image can be simulated on the basis of calculations in real numbers space. In this case there is a possibility to select the image contours, too.
