[Insight-users] x&y component of the gradient of an image

[Antonio Gómez Barquero]

Hello!

I would like to calculate the x and y component of the gradient of a 2D
image. As in MATLAB is calculated with [dT2,dT1] = gradient(T);

 

ReaderType::Pointer T_g            // image 

                FilterType::Pointer gradientFilter = FilterType::New();

                gradientFilter->SetInput( T_g->GetOutput());

                gradientFilter->Update();

With this sentence, I get the result, but I want to have the x-component and
the y-component

gradientFilter->GetOutput()

Is there any method to extract it? I am looking for it but I have no
positive result!

 

Thanks so much

 

Antonio
