Matt,
do you plan to correct the actual document?
https://itk.org/ItkSoftwareGuide.pdf
In the text, in the section 4.1.4, pages 41 and 42 :"A pixel is considered to
be the rectangular region surrounding the pixel center holding the datavalue.
This can be viewed as the Voronoi region of the image grid, as illustrated in
the right sideof the figure. Linear interpolation of image values is performed
inside the Delaunay region whosecorners are pixel centers."
these statements "Voronoi region of the image grid" and "Delaunay region whose
corners are pixed centers" - should go.
the image 4.1 "Geometrical concepts associated with the ITK image", should be
redone too. In the image "Linear Interpolation Region Delaunay Region" and
"Pixel Coverage Voronoi Region" must be replaced,
This document is used and shared by many and should not include confusing
terminology.
Thanks again,

Thank you for efforts to improve the work, Celina. The ITK Software Guide is a
living document, and many students should continue to learn from the body of
knowledge that Luis poured out many years ago.
Here is a patch for the figure:

and the text:

Ah, I see
now, Celina. Thanks for sharing the screenshots.
How about removing the mention of
Voronoi region and Delaunay region from that location in the
text and changing the annotation in the text to "Pixel
Centered Region" and "Pixel-Corner Centered
Region"?

Hi Celina,
I only
see "Voronoi region" mentioned once
here:
https://github.com/
InsightSoftwareConsortium/ ITKSoftwareGuide/blob/
7eb1f6dda1e5bfe57938f53584113e e771b298a7/SoftwareGuide/
Latex/DesignAndFunctionality/
HybridSegmentationMethods.tex
Perhaps we just replace
"Voronoi region" with
"region"?
Other
improvements to make the language more accurate / precise
are welcome.
Thanks,Matt

Hello Matt,
thank
you for your email...
I
agree it - but this one of the fundamendat geometric
constructs used in the Guide - that is just
ill-named...
How
can we name it differently.... definitely, not as Voronoi
region, nor Delaunay region (completely wrong)
-let
us discuss,
Best,
Celina

Dear
All
(I
have emailed separately Bill Schroeder at Kitware)
I
am very happy that ITK Toolkit has been thriving over so
many years. Kitware has done amazing job to maintain it and
to expand it.
Still,
I am trying to contact the main co-authors of the currect
ITK Software Guide.
I
am writing about the usage of "Voronoi Region"
terminology in the recent editions of the ITK Software guide
- that is very odd and not in agreement with how Voronoi
Diagram, that is one of the fundamental geometric
structures, is defined:https://www.cs.ucsb. edu/~suri/
cs235/Voronoi.pdf
Could
you please email me - I would like to suggest that if we
want to use as "geometrical concepts associated with
the ITK image" "Voronoi region" in a form
what I consider a degenerative representation of it - then
maybe it would be wise to name it differently. Not to
mention the usage of another oddity: Delaunay Region -
what is it? Voronoi Diagram and its dual, Delaunay
Triangulation are classic geometric constructs that require
that the points, in the Voronoi diagram, the Voronoi points,
satisfy:
"Non-degeneracy
Condition: Assume no 4 cocircular points, and no 3
collinear."
This
is violated in the construct included in the Guide and
referred to as Voronoi Region and Delaunay Region.
I
don't mind that the guide is not including any more my
original hybrid segmentation contribution that included
Voronoi Diagram classification https://core. ac.uk/download/
pdf/27299860.pdfI
woudl like to ask you to discuss what can be done with
possibly correctingthe odd terminology,
looking
forward to hear from
Best
