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.
