Abstract

We propose new approach for THz image quality enhancing using correlation function (convolution function) between Fourier transform of the image under consideration and Fourier transform of a standard image which can be enough complex. It is very important to stress that a standard image choosing allows us to remove essentially spurious parts of the image.

We discuss one more possibility to remove noise from background of the image as well as possibility of the image decomposition and its reconstruction.
