\subsection{Edge detection}  Two examples of complex images are included here as illustrations of edge detection using the \text{skv} algorithm.They are chosen to cover a range of image types and different degrees of 'crowding' and complexity.  More results are available in the accompanying additional material and moving images are available at the authors YouTube channel.
