IGRAPH
if-demo --- demostrate an endless skeletonization demo
DESCRIPTION
The if-demo igraph shows how the if operator may be used to
produce a skeletonization of a greyscale image. The memory operator
is used to recall the original image to restart the igraph causing
an infinite demo loop which can only be stopped using the Run menu.
The skeleton operator receives a binary image and outputs a new
binary image where binary regions are reduced by a single pixel around
there boundaries. The lower output on the skeleton operator tells
us how many pixels were removed. Until this value is zero, the skeleton
operator must be called again to converge upon medial axes of the
original binary regions. The if operator is used to check the pixelsRemoved
output to determine the flow of control.
