Dear<br clear="none">
All<br clear="none">
(I<br clear="none">
have emailed separately Bill Schroeder at Kitware)<br clear="none">
I<br clear="none">
am very happy that ITK Toolkit has been thriving over so<br clear="none">
many years. Kitware has done amazing job to maintain it and<br clear="none">
to expand it.<br clear="none">
Still,<br clear="none">
I am trying to contact the main co-authors of the currect<br clear="none">
ITK Software Guide.<br clear="none">
I<br clear="none">
am writing about the usage of "Voronoi Region"<br clear="none">
terminology in the recent editions of the ITK Software guide<br clear="none">
- that is very odd and not in agreement with how Voronoi<br clear="none">
Diagram, that is one of the fundamental geometric<br clear="none">
structures, is defined:<a rel="nofollow" shape="rect" target="_blank" href="https://www.cs.ucsb.edu/~suri/">https://www.cs.ucsb. edu/~suri/</a><br clear="none">
cs235/Voronoi.pdf<br clear="none">
<br clear="none">
Could<br clear="none">
you please email me - I would like to suggest that if we<br clear="none">
want to use as "geometrical concepts associated with<br clear="none">
the ITK image" "Voronoi region" in a form<br clear="none">
what I consider a degenerative representation of it - then<br clear="none">
maybe it would be wise to name it differently. Not to<br clear="none">
mention the usage of another oddity: Delaunay Region -<br clear="none">
what is it? Voronoi Diagram and its dual, Delaunay<br clear="none">
Triangulation are classic geometric constructs that require<br clear="none">
that the points, in the Voronoi diagram, the Voronoi points,<br clear="none">
satisfy:<br clear="none">
"Non-degeneracy<br clear="none">
Condition: Assume no 4 cocircular points, and no 3<br clear="none">
collinear."<br clear="none">
This<br clear="none">
is violated in the construct included in the Guide and<br clear="none">
referred to as Voronoi Region and Delaunay Region.<br clear="none">
I<br clear="none">
don't mind that the guide is not including any more my <br clear="none">
original hybrid segmentation contribution that included<br clear="none">
