For two-dimensional case the Gibbs phenomenon significantly reduces the quality of images processing for most popular graphic standards because they use a finite sum of harmonics. Distortion occurs on the borders of contrast' sharp change and leads to the appearance of false optical shadows. It is very bad for the analysis quality when processing the results of x-ray and sonar studies. We suggest using the two-dimensional Padé-type approximants method we developed earlier to reduce the Gibbs phenomenon for the harmonic two-dimensional Fourier series. The scheme of application of the method and its effectiveness are analyzed. [ABSTRACT FROM AUTHOR] |
