LevelsetCommand Constructor(int,int)

Summary

Initializes a new LevelsetCommand class object with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public LevelsetCommand( 
   int lambdaIn, 
   int lambdaOut 
)

- (instancetype)initWithLambdaIn:(NSInteger)lambdaIn lambdaOut:(NSInteger)lambdaOut NS_DESIGNATED_INITIALIZER;

public LevelsetCommand( 
   int lambdaIn, 
   int lambdaOut 
);

public: 
LevelsetCommand(  
   int lambdaIn, 
   int lambdaOut 
)

__init__(self,lambdaIn,lambdaOut) # Overloaded constructor

Parameters

lambdaIn
Represents the weight of moving the contour inside. The default value is 1.

lambdaOut
Represents the weight of moving the contour outside. The default value is 1.

Remarks

Equal values for lambdaIn and lambdaOut allow the algorithm to decide whether to shrink or expand the selected region.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void LevelsetConstructorExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   //Load an image 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE3.dcm")); 
 
   //Add region to the image to start the level set function from. 
   LeadRect region = new LeadRect(200, 200, 100, 50); 
   image.AddRectangleToRegion(null, region, RasterRegionCombineMode.Set); 
 
   //Prepare the command 
   LevelsetCommand command = new LevelsetCommand(1, 1); 
   command.Run(image); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";
