SigmaCommand Constructor(int,int,float,bool)

Summary

Initializes a new SigmaCommand class object with explicit parameters.

Syntax
C#
VB
C++
public SigmaCommand( 
   int dimension, 
   int sigma, 
   float threshold, 
   bool outline 
) 
Public Function New( _ 
   ByVal dimension As Integer, _ 
   ByVal sigma As Integer, _ 
   ByVal threshold As Single, _ 
   ByVal outline As Boolean _ 
) 
public: 
SigmaCommand(  
   int dimension, 
   int sigma, 
   float threshold, 
   bool outline 
) 

Parameters

dimension
Dimensions of the neighborhood used for filtering.

sigma
Number of Standard Deviations of the kernel calculated pixels must be within.

threshold
Minimum percentage of pixels included to the number of pixels in the kernel.

outline
Whether the central pixel is included in the calculation of the filter or not.

Example

Runs the SigmaCommand on the Image.

C#
VB
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void SigmaConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
   // Prepare the command 
   // Apply a sigma filter with a neighborhood of 5x5 pixels, sigma of 2, threshold of 0.2, and non outline aware. 
   SigmaCommand command = new SigmaCommand(5, 2, 0.2f, false); 
   command.Run(image); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images"; 
} 
Imports Leadtools 
Imports Leadtools.Codecs 
Imports Leadtools.ImageProcessing.Core 
 
Public Sub SigmaConstructorExample() 
   Dim codecs As New RasterCodecs() 
   codecs.ThrowExceptionsOnInvalidImages = True 
 
   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")) 
 
 
   Dim command As SigmaCommand = New SigmaCommand(5, 2, 0.2F, False) 
   command.Run(leadImage) 
 
End Sub 
 
Public NotInheritable Class LEAD_VARS 
   Public Const ImagesDir As String = "C:\Users\Public\Documents\LEADTOOLS Images" 
End Class
