Export data

I have two silly questions please:

1) I am trying to get data from a itk::Image. I found  the below one, but not my requirement. Can any one tell me is there a facility to import data from an itk::Image type to C array?

ImportImageFilter provides a mechanism for importing data into an itk::Image. ImportImageFilter is an image source, so it behaves like any other pipeline object. what abt other way?

2) Is it possible to find the Mean, variance and other statistical values of a given volume using itk

Thanx in advance

Suresh

Hi Suresh,

Please look at the ITK Tutorials

   http://www.itk.org/HTML/Tutorials.htm

There is a full tutorial on how to
integrate ITK with your application

http://www.itk.org/CourseWare/Training/GettingStarted-V.pdf

It includes a detailed explanation on how to
convert ITK images into C-arrays, back and forth.

    Regards,

      Luis

You could write a simple iterator that does the job for you.

  IteratorType it( image, image->GetBufferedRegion() );
  it.GoToBegin();
  while( !it.IsAtEnd() )
      {
      *cdata = it.Get();
      ++it;
      ++cdata;
      }
