Hi Motes,<br><br>Something that comes to mind is that you could mark the closest <br>pixels to your control points in the image that you are saving.<br><br>E.g. if you are using a CT image, you could use values around <br>
2000 to highlight the closest pixel to every control point.<br><br>A second option is that you could create an itkMesh with these<br>points, save it as a vtkPolyData in a .vtk legacy file by using the<br>itkVTKPolyDataWriter, and load it into Paraview, along with your <br>
2D image, then use the Glyph filter on the loaded vtkPolyData.<br><br>You may also find useful this paper from the Insight Journal:<br><br><div class="title">"Gridding Graphic Graticules"</div>

I am using one of the basic BSplineDeformableTransform examples on some 2D CT images of a brain.<br><br>Now for each 5 or 10 iteration I would like to view the currently registered image and the corresponding BSpline controlpoints (deformation vectors).<br>
<br>Are there any functionality in ITK that deals with this kind of visualization of registered images in progress and the corresponding controlpoints (deformation vectors)?<br>
</blockquote></div><br><br><br><br><br><br><br></div></div>Ok I have now written some code that writes the registered image to disk after a sequence of N iterations.<br>
<br>
In the future I hope to enable movement of control points in my
application. Therefore I would also like to plot the current position
of the control points on the current registered image.<br>
<br>
I am working on the following idea. When I store the current registered
image, I write the position of the control points to a file.<br>
<br>
Later I can (hopefully) in eg. gnuplot load the image and read in the
corresponding control points and plot them on top of the image.<br>
<br>
If anyone know of a better/easier way (maybe ITK already has examples showing this?) they are most welcome to give suggestions!<br>
