gives the morphological dilation of image with respect to the structuring element ker.

gives the dilation with respect to a range-r square.

applies dilation to an array of data.

Details and OptionsDetails and Options

  • Dilation works with arbitrary 2D and 3D images, operating separately on each channel, as well as data arrays of any rank.
  • The structuring element ker is a matrix containing s and s.
  • Dilation[image,r] is equivalent to Dilation[image,BoxMatrix[r]].
  • The structuring element is automatically padded with zeros to have odd dimensions.  »
  • Dilation takes a Padding option that specifies the values to assume for pixels outside the image.
  • By default, Padding0 is used for images, corresponding to pixel value 0 for all channels.
