Dilation

Dilation
gives the morphological dilation of image with respect to the structuring element ker.
Dilation
gives the dilation with respect to a range r square.
MORE INFORMATION
  • Dilation works with binary, grayscale, and other images.
  • The structuring element ker is a matrix containing s and s.
  • 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, corresponding to pixel value for all channels.
