CLAHECommand Constructor(float,int,float,int,CLAHECommandFlags)

Summary

Initializes a new CLAHECommand class object with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public CLAHECommand( 
   float Alpha, 
   int Tilesize, 
   float Tilehistcliplimit, 
   int Binnumber, 
   CLAHECommandFlags flags 
)

- (instancetype)initWithAlpha:(float)alpha tilesNumber:(NSInteger)tilesNumber tileHistClipLimit:(float)tileHistClipLimit binNumber:(NSInteger)binNumber flags:(LTCLAHECommandFlags)flags NS_DESIGNATED_INITIALIZER;

public CLAHECommand( 
   float alpha,  
   int tileSize,  
   float tileHistClipLimit,  
   int binNumber,  
   int flags 
)

public: 
CLAHECommand(  
   float Alpha, 
   int Tilesize, 
   float Tilehistcliplimit, 
   int Binnumber, 
   CLAHECommandFlags flags 
)

__init__(self,Alpha,Tilesize,Tilehistcliplimit,Binnumber,flags) # Overloaded constructor

Parameters

Alpha
Non-negative real scalar specifying a distribution parameter.

Tilesize
Positive integer specifying the size of the tiles.

Tilehistcliplimit
A real scalar in the range [0, 1] that specifies the contrast enhancement limit. Higher numbers result in more contrast.

Binnumber
(Multiple of 2) integer in the range [2, 1024] that specifies the number of bins for the histogram used when building a contrast-enhancing transformation.

flags
Flags specifying the desired histogram shape for the image tiles.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void CLAHEConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE3.dcm")); 
   string destFileName = Path.Combine(LEAD_VARS.ImagesDir, "CLAHERes.Tif"); 
 
   // Prepare the command 
   CLAHECommand command = new CLAHECommand(0.65f, 6, 0.08f, 6, CLAHECommandFlags.ApplyRayliehDistribution); 
 
   //Apply a CLAHE filter. 
   command.Run(image); 
 
   // Save it to disk 
   codecs.Save(image, destFileName, RasterImageFormat.Tif, 16); 
}
