Remarks

  • This operation can process the whole image or a region of the image.
  • The operation can be controlled by specifying the size of the neighborhood that is used for calculating each pixel value. For example, for 8x8, set the Dimension property (or the dimension parameter of the Constructor)to 8. Each pixel is replaced with the minimum value of its neighborhood.
  • This operation supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
  • This operation does not support 32-bit grayscale images.

Requirements

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family
