Hello dear ITK users;
In registration examples there is a couple of  variables which is called Versor;I couldn't understand what these variables indicate. Translation indicates that how much moving image will be translated through the x,y,z axis. But What about Versor? Is it about rotation 
Here is the part of an example:
// Print out results
//
std::cout << std::endl << std::endl;
std::cout << "Result = " << std::endl;
std::cout << " versor X = " << versorX << std::endl;
std::cout << " versor Y = " << versorY << std::endl;
std::cout << " versor Z = " << versorZ << std::endl;
std::cout << " Translation X = " << finalTranslationX << std::endl;
std::cout << " Translation Y = " << finalTranslationY << std::endl;
std::cout << " Translation Z = " << finalTranslationZ << std::endl;
std::cout << " Iterations = " << nmbrOfIterations << std::endl;
std::cout << " Metric value = " << bestValue << std::endl;

Tony
