Logarithmic transform coefficient histogram matching with spatial equalization
SPIE Proceedings, 2005In this paper we propose an image enhancement algorithm that is based on utilizing histogram data gathered from transform domain coefficients that will improve on the limitations of the histogram equalization method. Traditionally, classical histogram equalization has had some problems due to its inherent dynamic range expansion. Many images with data

Difference of Sums Containing Products of Binomial Coefficients and Their Logarithms
SIAM Review, 2006Properties of the difference of two sums containing products of binomial coefficients and their logarithms which arise in the application of Shannon's information theory to a certain class of covert channels are deduced. Some allied consequences of the latter are also recorded.

Logarithmic coefficients of locally univalent functions
1989In this paper the authors prove a bound for the coefficients of \(\log f'(z)=\sum_{n=1}^ \infty \gamma_ n z^ n\) for some locally univalent function \(f\) of the unit disk for which there is a representation \[ f'(z)=s'(z)\cdot \exp\{-2\int_ 0^{2\pi}\log{{1- \omega(z)e^{it}} \over {1-\omega(0)e^{it}}}d\mu(t)\} \] where \(s(z)=z+\dots\) is a normalized ...

Envelope Correlation Coefficient for Logarithmic Diversity Receivers Revisited
IEEE Transactions on Communications, 2007The analysis of the envelope correlation coefficient for logarithmic diversity receivers, given by de Neumann (de Neumann, 1989) for one Rayleigh fading branch in isotropic scattering environments (two independent real Gaussian branches), is extended in this letter to the general case where a maximum ratio combiner (MRC) operates on M ges 1 independent

Logarithmic coefficients of univalent functions
2000Let \(S\) be the class of functions \(f\) analytic and univalent in the unit disc \(\Delta= \{z\in \mathbb{C}:|z| {1\over n}\). Also, he is proving some results related to a conjecture of Milin on the logarithmic coefficients of functions in the class \(S\) and gives some applications of them to obtain upper bounds on the integral means of these ...
