LambdaConnectednessCommand Class

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

Object Model

Syntax

public class LambdaConnectednessCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

public sealed class LambdaConnectednessCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTLambdaConnectednessCommand : LTRasterCommand

public class LambdaConnectednessCommand extends RasterCommand

function Leadtools.ImageProcessing.Core.LambdaConnectednessCommand()

public ref class LambdaConnectednessCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration

Public Class LambdaConnectednessCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage

Dim instance As LambdaConnectednessCommand

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

C#
Visual Basic

Imports Leadtools
Imports Leadtools.Codecs
Imports Leadtools.ImageProcessing.Core

   
Public Sub LambdaConnectednessCommandExample()
   Dim codecs As RasterCodecs = New RasterCodecs()
   codecs.ThrowExceptionsOnInvalidImages = True
   'Load an image
   Dim image As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\NaturalFruits.jpg"))

   'Prepare the command
   Dim command As LambdaConnectednessCommand = New LambdaConnectednessCommand()
   command.Lambda = 950

   'Apply
   command.Run(image)
End Sub

Public NotInheritable Class LEAD_VARS
Public Const ImagesDir As String = "C:\Users\Public\Documents\LEADTOOLS Images"
