Erosion

Erosion[image,ker]
gives the morphological erosion of image with respect to the structuring element ker.

Erosion[image,r]
gives the erosion with respect to a range-r square.

Erosion[data,]
applies erosion to an array of data.

Details and OptionsDetails and Options

  • Erosion 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.
  • Erosion[image,r] is equivalent to Erosion[image,BoxMatrix[r]].
  • Erosion automatically adds zeros to structuring elements so that they have odd dimensions. »
  • Erosion takes a Padding option that specifies the values to assume for pixels outside the image.
  • By default, Padding->1 is used for images, corresponding to pixel value for all channels.
