Dilation(morphological operator) for images.
The dilation function takes two pieces of data as inputs. The first is the input image to be morphed, and the second is the mask indicating the neighborhood around each pixel to match.
In dilation, for each pixel, the mask is centered at the pixel. If the center pixel of the mask matches the corresponding pixel on the image, then the mask is accepted. If the center pixels do not matches, then the mask is ignored and no changes are made.
For further reference, see: Dilation (morphology)
Sample input and output are shown below:
C Interface for image dilation (max filter)
|[out]||out||array is the dilated image|
|[in]||in||array is the input image|
|[in]||mask||is the neighborhood window|
maskis all ones, this function behaves like max filter
