KMeansCommand Class

Summary

public class KMeansCommand : RasterCommand

Remarks
  • K-Means is an algorithm for analyzing data. Each observation gets placed in the cluster having the nearest mean.
  • The number of clusters returned are less than or equal to the number of input clusters.
  • If the image contains fewer clusters than the number of input clusters, this command will return the image colors in the OutCenters property.
  • This command can only process entire images. It does not support regions.
  • This command converts image to 8-bit grayscale.
  • This command supports signed/unsigned images.
  • 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 in the Document/Medical Imaging toolkits.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void KMeansCommandExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   //Load an image 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "cannon.jpg")); 
 
   //Prepare the command 
   KMeansCommand command = new KMeansCommand(); 
 
   command.Clusters = 7; 
   command.Type = KMeansCommandFlags.KMeans_Random; 
 
   //Apply  
   command.Run(image);
