[vtkusers] Beginner in c++ imaging toolboxes

Howdy.

I think you are  confusing the functionality of presentation vs.
pre-processing, and re-construction in 3D vs. 2d processing.

ITK is a package built on VTK. ITK is for segmentation and 3d
reconstruction of (typically) tomographic and 3D point data.
It is a complete system built on the VTK libraries.

The VTK libraries have 'some' 2D image processing built in,
but also have an enormous amount of 3D processing and presentation.
Indeed, many people refer to VTK as a smart library built on
top of the OpenGL 3D library.

Intel Performance Primitives are, generally, 2D filters, primitives,
and blobbing and object extraction operators (optimized for Intel
processors, naturally...) typically used in 2D image processing.
This might be used for a 'mid end' software between a camera
and a target tracking or feature extraction program.

The VXL library sounds, like its web page suggests, a lot like
the IPP.

VNL, is it is what you said (I did not bother to check it out
on the web) sounds like the numeric 'back end' to VXL.

So there you go. If you are looking towards doing medical
data reconstruction and display/presentation, ITK and VTK
are probably more up your alley.

Just an opinion. Any seconds or counters?

Best of luck on your degree work.
