[vtkusers] adding noise to vtkImageData

[Prathamesh Kulkarni]

Hello all,

I need to add different kinds of noise to a vtkImage. I have looked at
vtkImageNoiseSource and vtkMath::Random().

Of these,

vtkImageNoiseSource only produces a uniform noise output - is there a way
(already existing in vtk) to have a different underlying noise distribution?

vtkMath::Random produces a random number - what is the internal distribution
used here?


Apart from these, are there any other better ways to adding noise to
vtkImages?


Thanks in advance,


Prathamesh
