This repository contains ITK filters to estimate a strain tensor field from a displacement field or a spatial transformation.

To install the Python package:

pip install itk-strain

To build the C++ module, either enable the CMake option in ITK's build configuration:

Module_Strain:BOOL=ON

Or, build the module as a separate project against an ITK build tree:

git clone https://github.com/KitwareMedical/ITKStrain
mkdir ITKStrain-bulid
cd ITKStrain-build
cmake -DITK_DIR=/path/to/ITK-build ../ITKStrain
cmake --build .
