class DeinterlaceCommand(RasterCommand):

Remarks

This command deinterlaces video source images by removing the black lines. It proceeds by merging lines in the image and/or blending them. Different options are available through the use of flags.
This command 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 signed data images.
This command does not support 32-bit grayscale images.

For more information, refer to Removing Noise.

   // Prepare the command 
   DeinterlaceCommand command = new DeinterlaceCommand(); 
   command.Flags = DeinterlaceCommandFlags.Smooth | DeinterlaceCommandFlags.Odd; 
   // Remove odd lines smoothly. 
   command.Run(image);
