BinaryThinningImageFilter3D takes too much time

[mcgreey]

When I extract the centerline from a binary three-dimensional array with a size of 512 x 512 x 600, it takes approximately 104 seconds. Is this normal? What should be the normal time consumption? The version is 5.4.3, and it is compiled in the release mode.

May i know how you use BinaryThinningImageFilter3D in C++? I use ITK4.13 and VS2019 to build, after generate in cmake3.16, i can find Thickness3D-all in ITK.sln, however after build and install steps, i counln't find itkBinaryThinningImageFilter3D.h in my CMAKE_INSTALL_PREFIX file, thus your usage experience is very helpful to me, thx.
