KMeansCommand Constructor(int,KMeansCommandFlags,RasterColor[])

Summary

Initializes a new KMeansCommand class object with explicit parameters.

Syntax
C#
VB
Java
Objective-C
C++
Public Function New( _ 
   ByVal Clusters As Integer, _ 
   ByVal Type As KMeansCommandFlags, _ 
   ByVal InCenters() As RasterColor _ 
) 
- (instancetype)initWithClusters:(NSInteger)clusters 
                            type:(LTKMeansCommandFlags)type 
                       inCenters:(nullable NSArray<LTRasterColor *> *)inCenters 
public KMeansCommand( 
   int Clusters,  
   KMeansCommandFlags Type,  
   ArrayList<RasterColor> InCenters 
) 

Parameters

Clusters
Number of output clusters or colors in the output image.

Type
Flag that determines which initializing algorithm to use when choosing the initial centers for the clusters.

InCenters
If the Type is KMeans_UserDefined, InCenters should be a reference to an array of RasterColor values that represents the initial centers.

Remarks

RasterColor[] InCenters should be null if Type is KMeans_Random or KMeans_Uniform. If Type is KMeans_UserDefined, RasterColor[] InCenters should be filled with the initial centers for the clusters.

Example
C#
VB
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void KMeansConstructorExample() 
{ 
   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(7, KMeansCommandFlags.KMeans_Random, null); 
 
   command.Run(image); 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images"; 
} 
Imports Leadtools 
Imports Leadtools.Codecs 
Imports Leadtools.ImageProcessing.Core 
 
Public Sub KMeansConstructorExample() 
   Dim codecs As RasterCodecs = New RasterCodecs() 
   codecs.ThrowExceptionsOnInvalidImages = True 
 
   'Load an image 
   Dim image As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "cannon.jpg")) 
 
   'Prepare the command 
   Dim command As KMeansCommand = New KMeansCommand(7, KMeansCommandFlags.KMeans_Random, Nothing) 
   command.Run(image) 
 
End Sub 
 
Public NotInheritable Class LEAD_VARS 
   Public Const ImagesDir As String = "C:\Users\Public\Documents\LEADTOOLS Images" 
End Class
