[Insight-users] volview plugin

[Luis Ibanez]

Hi Guorong,

It is great to hear that you are trying the VolView plugins.
Curiously enough, writing plugins for VolView is the simplest
way of testing a prototype for an ITK pipeline.

You may find that there are too many ITK Level Set plugins
in VolView.... but other users think there are not enough  :-)

Parameter tunning is an unavoidable problem for the setting
of the VolView plugins, given that they are provided as a
generic segmentation tool that you can use for segmenting
the Abdomial Aorta from CT, or the Gray Matter from an MRI
or cells from Electron Microscopy Tomography.

The only way to get over the parameter fitting problem is
to write application specific plugins. For example to take
one of the LevelSet plugins and fine tune its parameteres
for segmenting Liver from CT. Then fix those parameters
and expose only the minimum possible number of other
remaining free parameters.  These application-specific
plugins are the way to go in order to take advantage of
the combined capabilities of ITK and VolView.  Of course,
it means that you have to figure out correct parameters
in an initial stage.


If you give us a more detailed description of the problem
you are trying to solve with VolView + ITK plugins we will
be happy to assist you in finding an appropriate combination
of ITK filter and in fine tunning their parameters. Just post
a more detailed message to the list.


VolView does not support 2D images. It has been designed
from the beggining for processing 3D image. As you probably
know, VolView originated as a tool for providing high quality
volume rendering, which of course doesn't makes sense for 2D
images.


You are welcome to post any questions regarding VolView
plugins into this list.


The perfect place for sharing your plugins with other is the
INSIGHT JOURNAL which will open its doors to submissions in
July 1st.


You can share your plugins in binary form, or in source code,
and accompany them with a short PDF describing their functionality.
If you decide to share plugins by publishing them in the INSIGHT
JOURNAL then you must provide source code.


Please let us know if you have further questions,


   Thanks


      Luis

>      1. Lack of documentation about plugins. Users may confused or even don't know how to use them which is complex, for example, levelset segmentation plugins. There are too many parameters which I am not sure what it is realy works. I confess although I tried many times I can't use some powerful segmentation plugins to have the result I want. What's more, everytime I run the filter, it takes a lot of time because of the 3D data. I read thought the VolView2.0 User's Guide, there's only terse introduction in the section Filters. 
>      2. It seems Volview does not support 2D image processing explictly, that is, user can not open a single 2D image and then do segmentation or registraion for example. It doesn't matter, I can write a plugin which can extract one slice from the 3D volume. But I want to know if I have only a 2D image, how can I deal with it in volview.
>      3. Is there community or forum about volview plugins? Or if I have write a plugins how can I share it with others?
>      All in all, ITK and VolView facilitate my research work very much and I really appreciate the poineer and developers with this work. Thanks for their hard work and passion for medical image processing. Let's join this great job and do our best to make this career more and more better.
