LambdaConnectednessCommand Class

Summary

Performs image segmentation using a special region-growing algorithm called Lambda Connectedness.

Syntax

Objective-C

C++

Java

public class LambdaConnectednessCommand : RasterCommand

Public Class LambdaConnectednessCommand  
   Inherits RasterCommand

@interface LTLambdaConnectednessCommand : LTRasterCommand

public class LambdaConnectednessCommand extends RasterCommand

public ref class LambdaConnectednessCommand : public RasterCommand

Remarks

Lambda-connectedness is a technique used to find the connectivity between an image's pixels and then clusters them into groups.
Low values for lambda can result in one region.
High values for lambda can result in an over-segmented image.
This function 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.
This command supports signed/unsigned images.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void LambdaConnectednessCommandExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   //Load an image 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\NaturalFruits.jpg")); 
 
   //Prepare the command 
   LambdaConnectednessCommand command = new LambdaConnectednessCommand(); 
   command.Lambda = 985; 
 
   //Apply 
   command.Run(image); 
}
