Dilation

Dilation[image, ker]
gives the morphological dilation of image with respect to the structuring element ker.
Dilation[image, r]
gives the dilation with respect to a range r square.
  • Dilation works with binary, grayscale and other images.
  • The structuring element ker is a matrix containing 0s and 1s.
  • Dilation automatically adds zeros to structuring elements so that they have odd dimensions.
  • If multiple image channels are present, Dilation operates on each of them separately.
  • Dilation takes a Padding option that specifies the values to assume for pixels outside the image.
  • The default setting is Padding->0, corresponding to pixel value 0 for all channels.
