[Insight-users] How to transfer ITK image to matrix or vector ?

[Sergio Vera]

Hello Yang,

Reply to both, or at least to the mailing list address so all the users can
participate in the thread.

Best, safest and fastest way to access pixels in ITK are Image iterators:
have a look at the chapter 11 from the ITK software guide for more info and
examples:
http://www.itk.org/ItkSoftwareGuide.pdf

with the iterator you can traverse the image reading a voxel each time, that
you can copy to your matrix

Also, what do you mean when you ask for "testing codes in ITK"?
