Over the past two decades, there have been various studies on the distributions of the DCT coefficients for images. However, they have concentrated only on fitting the empirical data from some standard pictures with a variety of well-known statistical distributions, and then comparing their goodness of fit. The Laplacian distribution is the dominant choice balancing simplicity of the model and fidelity to the empirical data. Yet, to the best of our knowledge, there has been no mathematical…

Analyzing the Effect of JPEG Compression on Local Variance of Image Intensity

The theoretical analysis presented in this paper provides some new insights into the behavior of local variance under JPEG compression, which has the potential to be used in some areas of image processing and analysis, such as image enhancement, image quality assessment, and image filtering.

Distributions of the Two-Dimensional DCT Coefficients for Images

From a simulation of the DCT coding System it is shown that the assumption that the coefficients are Laplacian yields a higher actual output signal-to-noise ratio and a much better agreement between theory and simulation than the Gaussian assumption.

On the distribution of the DCT coefficients

A statistical study to improve the image compression rate in discrete cosine transform (DCT) based methods and especially for compression methods which are defined in JPEG norm using a battery of parametric and non-parametric fit-tests and laws such as those of Cauchy, Laplace, Gauss and a mixture distribution of Laplace and Gaussian.

It is shown that the difference of information between the approximation of a signal at the resolutions 2/sup j+1/ and 2/Sup j/ can be extracted by decomposing this signal on a wavelet orthonormal basis of L/sup 2/(R/sup n/), the vector space of measurable, square-integrable n-dimensional functions.
