Remarks

  • The image is divided into two parts, inner and outer according to the values of the LowThreshold property and the HighThreshold property.
  • The operation can process 2 or more channels at a time by OR-ing two or more flags.
  • 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 command 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
