| Fourier Analysis of the Texture of High-Definition Images |

| This paper presents the results of measuring the signal-to-noise ratio at the boundary of object contours in high-definition images after compression of the original digital stream based on the Fourier transform and the discrete cosine transform. It is shown that when choosing the threshold for limiting the spectral components of the image, one should not only focus on the frequency, but also take into account the magnitude of the differences in the brightness signal in areas of low-contrast textures. |
