The NCG is a good statistic for block based watermarking which uses geometric warping. The NCG-strength (given by Lx and Ly) enables the estimation of the robustness of the NCG - x,y-cordinates to lossy compression. A higher strength yields a higher robustness. To embedd watermark bits the NCG -...

Fleiss'es kappa is a generalization of Scott's pi statistic, a statistical measure of inter-rater reliability. It is also related to Cohen's kappa statistic. Whereas Scott's pi and Cohen's kappa work for only two raters, Fleiss'es kappa works for any number of raters giving categorical ratings...

Converts normally distributed z-statistic to one- or two-tailed p-valueby integrating the standard normal pdf. If no "tails" value is specified, z2p computes the two-tailed value by default. The output p is the same size as z, which can be a scalar, vector, or matrix. Inputs:z: normally...

Anderson and Darling (1952, 1954) introduced a goodness-of-fit statistic to test the hypothesis that a random sample comes from a continuous population with a specified distribution function. It is a modification of the Kolmogorov-Smirnov (K-S) test and gives more weight to the tails than the K-S...
