12/3/6.htm VB example of s-psi curve
When you click 'edge', a shape vaguely resembling an animal profile is
'stitched' by the edge-tracing routine. A resulting s-psi cure is
sshown in another window. You can smooth this curve, while seeing
the reconstructed shape. You can also 'pack' it, reducing the
number of points to 256. The reconstructed shape is still
recognsable.
The VB6 .frm file and also an .exe version are in this zip file.
