[Insight-users] Region Growing Segmentation Example

[Luis Ibanez]

Hi Zein,

The text files for the seed point are only for output.

The seed point is actually selected by clicking with
the mouse on the image that is displayed by the button
"Homogeneous Image" at the center of the GUI.  This
will show you the image after the anisotropic difussion
smoothing has been applied to it.

Once you see the image, you can select different
slices with the vertical slider at the right side
of the image, or by using the "<" and ">" keys.
Clicking on the "h" key will show a help message
about the controls for the image viewer.

Once you find a slice that is interesting, click
with the mouse (left button) on the image and the
coordinates of the seed point will appear on the
text fields. A cross line will also be displayed
on the viewer.

The kind of edge-preserving smoothing can be selected
by clicking on the green romboid on the blue lines
connecting the buttons of the anisotropic filters
with the "homogeneous" image button.

We are implementing a much better method for
interactive selection of seed points using the
3DWidget classes currently available in VTK.


  Regards,


   Luis
