SegmentCommand Class

Summary
Divides the image into segments where each segment's pixels have approximately the same color (homogenous color). This command is available in the Imaging Pro and above toolkits.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public class SegmentCommand : RasterCommand 
@interface LTSegmentCommand : LTRasterCommand 
public class SegmentCommand 
    extends RasterCommand 
public ref class SegmentCommand : public RasterCommand   
class SegmentCommand(RasterCommand):
Remarks
  • This command divides the images into segments according to its pixel values . The segment shapes will be arbitrary. Adjacent pixels with approximately the same values are put together into homogenous segments. The command may be performed on the RGB and YUV color spaces.
  • 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.

Example

Run the SegmentCommand on an image.

C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void SegmentCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   SegmentCommand command = new SegmentCommand(); 
   command.Threshold = 20; 
   command.Flags = SegmentCommandFlags.Rgb; 
   //segment the image. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
