Hello, It appears that you are trying to use some code from my github extension:
https://github.com/blowekamp/itkOBBLabelMap I am not sure where to begin helping you. You didn't include the run-time error message, and your code fragment is missing key parts. Can you post a minimal compilable example which illustrates the problem? Sometime just narrowing down you code to this part help you figure out your issue. Do the tests for the extension pass for you? Are you able to run the example? https://github.com/blowekamp/itkOBBLabelMap/blob/master/test/itkOBBExample.cxx Brad On Nov 12, 2013, at 1:43 PM, elhadj meljane <[email protected]> wrote: > Hi all, > I am trying to use itk to select a component from a binary image.
