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[data,]
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]].
  • Dilation automatically adds zeros to structuring elements so that they 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 for all channels.
