Abstract

We investigate a new approach for the THz image quality enhancing using correlation function (convolution function) between Fourier transform of the image under consideration and Fourier transform of a standard image. Main difficulty of this approach concludes in choosing of the standard image in that way to see in its Fourier spectrum the spectrum harmonics of well-known forbidden objects. We compare the results of computer processing based on developing approach with the results which were obtained early using various other approaches. We discuss one more possibility to remove noise from background of the image as well as possibility of the image decomposition and its reconstruction.
