Image type for an ITK image from numpy array

Beginner Questions

Maybe itkImageRGBUC3 is not wrapped by default, so ITK implicitly converts it to scalar?

EDIT: the conversion RGB->Scalar usually uses luminance, so in this case you don’t need RGBToLuminanceImageFilter.

Also, does np.ascontiguousarray(np_image) give an RGB image?
