<div dir="ltr">I'm getting started with vtk and I'm still unable to solve a lot of<br>
problems.<br>
<br>
I'm trying to apply the vtk filter vtkImageDilateErode3D to a CT image but I<br>
can't obtain the result I'm looking for.<br>
In fact I expect the result to be a at least slightly different image but<br>
the output is instead an image identical to the one given as input (I even<br>
checked subtracting the two images with vtkImageMathematics and after the<br>
operation there's really nothing left!).<br>
I don't understand if the problem is in the setting of the Erode and Dilate<br>
values and in the kernel size or maybe in the function of the filter itself,<br>
i.e. I expect that the output image has something less compared to the<br>
original one after erosion and dilatation (what has been eroded "to the<br>
ground" canot be dilated back - is this correct?)<br>
<br>
Thank you in advance<br>
Sorry for the bad english<br>
