I am looking for papers and examples for volume segmentation. Bull people,
please, provide me the useful materials.
Thanks a lot.

What is your goal. Do some reserch or just need a simple solution

The volume segmentation is part of my current project. For a simple example,
I need to extract a human brain grey matter volume segment from the
3-D human brain gray-scale image. The process is done by highlighting a
volume of interested 2D region on the 3D gray-scale image, then the
corresponding 3D volume is extracted to a new window frame for viewing. In
addition, the extracted 3D volume is viewed as a color 3D image.
Anyone know certain papers(examples) related to my project, please,

.. for your way, you may use some AI classification method.
the selected region is the training dataset... there shoudl be many existing
ways to do the classification.
Kuan-Liu Ma has one paper in this year's Vis. Although that paper is mainly
about interface, you should be bale to find some refs there

example,

just a thought(ignore me if you think it's nonsense),
if you can bind some depth information with your 2d image pixel, say
a z-buffer value,maybe it's more easy to extract from 3d image data set
after you hightlight the 2d region. is that simple enough?:o)

for the volume rendering, it might be difficult to get the depth information.
All non-empty voxel will effect the z-buffer. but it would be interest if you
can find someway to get around it.... make soem information you can direct
index to the interested part of the volume.

yeah, i know what you mean, maybe the traditional z-buffer can't
handle such problem, but if we can us some kinda of 'volume'z-buffer,
say every non-empty voxel will have an index in this 'volume'z-buffer,
maybe we can archieve the goal. of course it's not efficient way, but
it might be good for realtime stuff after the preprocess.

could be implemented in software.
and Ester, any progress in your own volume work?

haven't got time to improve it yet, i'm working my ass off on
two course projects now, but i will make some imporvement later on,
maybe use it to render my project result, two thing i really want
to add are isosurface and self shadowing, did you touch levelset
before, i think it's better than marching cube when tracking moving
volume surface.

levelset is interesting, but way hard to implement,
for marching cube, its very easy if you use classes in
VTK.

still not clear how you highlight 2D ROI,
you mean on each single slice or on the 3D image?

yes, there are a lot realtime blobby programs around, all you
need to do is copying the predifined huge data table and indexing it.
