Dear MITK users,
the mitkCalculateGrayValueStatisticsTool throws an itk warning after use
(I'm using ITK 3.4), because the itk::MapContainer (histogram) is not
created using New().
WARNING: In
..\..\..\src\InsightToolkit-3.4.0\Code\Common\itkLightObject.cxx, line
203 LightObject (00E4EFFC): Trying to delete object with non-zero
reference count.
Attached there is a patch that adjusts the code for using the container
as an itk::Pointer.
Best,
Marius
