Figure~\ref{fig:gaborcoarse}(a) shows four Gabor patches with a spatial frequency of 20 cycles per frame and Figure~\ref{fig:gaborcoarse}(b) and (c) show the resulting \textsc{skv} representation at two window sizes. As can be seen in Figure~\ref{fig:gaborcoarse}(b) the 'hi-res' \textsc{skv}$_{50}$ produces a result which is not unlike the original, but with twice the spatial frequency; this is because each transition from black to white produces an 'onset' and an 'offset'. The 'lo-res' \textsc{skv}$_{10}$ in Figure~\ref{fig:gaborcoarse}(c) produces some blurring of onsets and offsets, so the frequency doubling is slightly less obvious, but the results are in many ways similar. In both cases the value of the  \textsc{skv} is largest in the areas of highest contrast.
