\section{Methods}  For results derived from monochrome images each pixel is defined by three values; two coordinates $i$ and $j$, the row and column positions of the pixel respectively, and a single value $k$ that is the value of the pixel on the gray-scale from 0 (black) to 1 (white). Images are processed on a pixel-by-pixel basis and the \textsc{skv} value of each pixels is calculated thus:  \begin{enumerate}  \item the number of pixels $m$ corresponding to half the required window size $n$ is calculated: $m = \floor(\frac{n}{2}) floor(\frac{n}{2})  \item   \item assemble the vector $\vec{k}_{j}$ of values for a horizontal window of $n$ contiguous pixels $k_{[i,j-; i,j+1; i,j+n-1]}$  \item repeat with $\vec{k}_{i}$, a vector of values for a vertical window of $n$ pixels $k_{[i,j; i+1,j; i+n-1,j]}$
