Distribution-based restoration of DCT coefficients
IEEE Transactions on Circuits and Systems for Video Technology, 2000Although it is established that the distribution of the discrete cosine transform coefficients can be modeled, it is not known how this knowledge can best be applied to improve the JPEG compression algorithms. We studied this problem by making modifications to both the JPEG baseline encoder and decoder separately.

Distribution of FRFT Coefficients of Natural Images
2015For the convenience of providing temporal and spectral information by a single variable, fractional Fourier transformation (FRFT) is more and more applied to image processing recently. This paper focuses on the statistical regularity of FRFT coefficients of natural images and proposes that the real and imaginary parts of FRFT coefficients of natural ...

Distribution of the Correlation Coefficient
1980The extraordinary interest in the correlation coefficient is evidenced by the number of papers and pages in statistical publications dealing with the correlation coefficient (see Table 1).
