[ITK] [ITK-users] Undefined references to methods of template classes

Fri Jan 16 02:02:24 EST 2015

Hi Matt.
I've already solved the texture features problem.
The solution is similar to that of the shape features. You must set a value
or values to the filter in order to be able to calculate the features. I've
used the SetPixelValueMinMax
<http://www.itk.org/Doxygen/html/classitk_1_1Statistics_1_1ScalarImageToTextureFeaturesFilter.html#a373867fa4b665bc5e4b56fea305ed774>()
method and everything OK.
Thank you very much for your support.
/Francisco
