The M –relative distance , denoted by ρ M is a generalization of the p –relative distance, which was introduced in [10]. We establish necessary and sufficient conditions under which ρ M is a metric. In two special cases we derive complete characterizations of the metric. We also present a way of extending the results to metrics sensitive to the domain in which they are defined, thus finding some connections to previously studied metrics. An auxiliary result of independent interest is an inequality…

Barrlund's distance function

This work proves that another function, studied by O. Dovgoshey, P. Hariri, and M. Vuorinen is a metric and gives upper and lower bounds for it.

Barrlund's distance function and quasiconformal maps

This work studies this Barrlund metric and gives sharp bounds for it in terms of other metrics of current interest and proves sharp distortion results for the Barrlund metrics under quasiconformal maps.

On the Mathematical Properties of the Structural Similarity Index

A series of normalized and generalized metrics based on the important ingredients of SSIM are constructed and it is shown that such modified measures are valid distance metrics and have many useful properties, among which the most significant ones include quasi-convexity, a region of convexity around the minimizer, and distance preservation under orthogonal or unitary transformations.

Apollonian isometries of planar domains are Möbius mappings

The Apollonian metric is a generalization of the hyperbolic metric, defined in a much larger class of open sets. Beardon introduced the metric in 1998, and asked whether its isometries are just the…

Optimal structural similarity constraint for reversible data hiding

This paper deduces the metric of the structural similarity constraint, and further it proves it does’t hold non-crossing-edges property, and constructs the rate-distortion function of optimal structural similarity constraints, which is equivalent to minimize the average distortion for a given embedding rate.

A new Möbius-invariant metric δG defined on an open set G⊂[Rmacron]n with at least two boundary points is introduced. This metric coincides with the hyperbolic metric if G is the unit ball. Some…

A monotonicity property of ratios of symmetric homogeneous means.

We study a certain monotonicity property of ratios of means, which we call a strong inequality. These strong inequalities were recently shown to be related to the so-called relative metric. We also…

The Power Mean and the Logarithmic Mean

In a very interesting and recent note, Tung-Po Lin [I] obtained the least value q and the greatest value p such that M <L<M P q is valid for all distinct positive numbers x and y where M (x +.y.)s…

The conjecture that the p-relative distance, $\varrho_p(\alpha,\tilde{\alpha})=|\alpha-\tilde{\alpha}| /{\sqrt[p]{|\alpha|^p+|\tilde{\alpha}|^p}}$, is a metric is proved.

Inequalities for Means

Abstract A monotone form of L′Hospital′s rule is obtained and applied to derive inequalities between the arithmetic-geometric mean of Gauss, the logarithmic mean, and Stolarsky′s identric mean. Some…
