[Insight-users] Manual drawing on fltkimage viewer display

[Suja S]

Thanks so much for the detailed answers ,Luis.
 I am developing a tool for brain tumor segmentation using ITK & FLTK.
 Presently it does region growing segmentation, but sometimes it is preferred to have a ROI drawn by the end user to include or exclude a particular region and also to edit the final segmented output. Right now we use a different tool to do the drawing and editing, but it will be a lot easier if it can be done in the fltk image viewer where the seed points are clicked. That will make it a complete tool for the end user.
 I would love to add these capabilities to the image viewer if someone can direct me. Do I change the code in InsightApplications/Auxillary for that?
Thanks again,
 Suja.

Hi Suja,

The FLTK image viewer is provided as a minimal viewer, but with the
decent capabilities of taking into account the pixel size of a medical
image and respecting the natural orientation of the image.


There are basic capabilities in the fltk viewer for selecting clicked
points, but not for marking regions of interest, or for performing
pixel editing.



For an application that provides those features, you may want to give
it a try to SNAP. This application is also distributed with ITK, in
the InsightApplications module. It requres VTK, ITK and FLTK.


SNAP is ultimately intended for performing LevelSet segmentations of
your images, but as a way of initializing those level sets, SNAP let
you define manual segmentations on a slice-by-slice basis. Of course,
you can simply use SNAP as a manual segmentation tool.

You can get binary versions of SNAP from its web site:

                 http://www.itksnap.org/

as well as Tutorial:

        http://www.itksnap.org/docs/Tutorial.html





Another tool that you may want to try is Slicer:

                    www.slicer.org

a tutorial for Slicer is available at:

             http://www.slicer.org/tutorial/

The source code is open, and binary version are also available
for download.




The capabilities that you describe are commonly requested by end
users, and it may be a good idea to put them together in a minimal
tool that can be shared with the community.



Please let us know if you have other questions.


     Thanks


        Luis
