On the distribution of the DCT coefficients
Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002The paper presents a statistical study in order to improve the image compression rate in discrete cosine transform (DCT) based methods and especially for compression methods which are defined in JPEG norm. It is realised extensively, using a battery of parametric and non-parametric fit-tests and laws such as those of Cauchy, Laplace, Gauss, and a ...

Distribution of Frame Coefficients
2016 9th International Symposium on Computational Intelligence and Design (ISCID), 2016Frame coefficients play an important role in the study of frame theory, which helps in the structural analysis of applications for frames. However, we know very little about the distribution of frame coefficients sequences. In this paper, we mainly study the distribution of the frame coefficients for vectors in a Hilbert space by using the minimum ...

The distribution of transformed concordance coefficients
Communications in Statistics, 1974Wood (1970) proposed a variance stabilizing transformation for coefficients of concordance of a set of rankings. The distributions of the transformed statistics are studied using sampling experiments, and the use of Beta-distributions, as approximations to the distributions of the untransformed statistics, is considered. Simple approximations appear to
