Resampled image with vector overlay of the most salient (weighted path
integral of length, scale and gradient magnitude) edges identified with
Scale Space Edges.
Contrast of edges (yellow) with background (grayscale) indicates relative normalized gradient at nearest edge point.
"Ghost" edges, for example around the pens/brushes in the cups at the
bottom, apprear to be sharpening artifacts.
