NumberOfPoints Property

Summary

This property is updated with the number of areas in the image actually found to be correlated to the correlation image.

Syntax

Objective-C

C++/CLI

Java

Python

public int NumberOfPoints { get; }

@property (nonatomic, assign, readonly) NSUInteger numberOfPoints;

public int getNumberOfPoints();

public: 
property int NumberOfPoints { 
   int get(); 
}

NumberOfPoints # get  (CorrelationCommand)

Property Value

Value that indicates the number of areas in the image actually found to be correlated to the correlation image. Its maximum value is the length of the Points array.

Example

Run the CorrelationCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void NumberOfPointsPropertyExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "clean.tif")); 
 
   // Prepare the command 
   RasterImage dstImage = image.Clone(); 
   CorrelationCommand command = new CorrelationCommand(); 
   command.CorrelationImage = dstImage; 
   command.Threshold = 70; 
   command.XStep = 1; 
   command.YStep = 1; 
   command.Points = new LeadPoint[90]; 
   // Apply the correlation filter. 
   command.Run(image); 
 
   MessageBox.Show("The number of points are:" + command.NumberOfPoints.ToString()); 
 
}
