Radius Property

Summary

Parameter used to determine the radius of the Gaussian filter used inside this function to smooth the image before the edges are extracted.

Syntax

Objective-C

C++/CLI

Python

public int Radius {get; set;}

@property (nonatomic, assign) NSInteger radius;

public:  
   property Int32 Radius 
   { 
      Int32 get() 
      void set(Int32 value) 
   }

Radius # get and set (CannyEdgeDetectorCommand)

Property Value

Parameter used to determine the radius of the Gaussian filter used inside this function.

Remarks

The Gaussian filter is not applied if the Radius is zero. The Radius should be zero if the image is clean.

Example

using Leadtools; 
using Leadtools.Codecs; 
 
using Leadtools.ImageProcessing.Core; 
 
public void CannyEdgeDetectorCommandExample()  
{      
       
   RasterCodecs codecs = new RasterCodecs(); 
       
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "cannon.jpg"), 0, CodecsLoadByteOrder.Bgr, 1, 1); 
   CannyEdgeDetectorCommand Canny = new CannyEdgeDetectorCommand(); 
   Canny.Radius = 1; 
   Canny.LowThreshold = 2; 
   Canny.HighThreshold = 5; 
   Canny.Channels = CannyEdgeDetectorCommandChannels.Master; 
   Canny.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "cannon_Canny.bmp"), Leadtools.RasterImageFormat.Bmp, 24, 1, 1, 1, Leadtools.Codecs.CodecsSavePageMode.Overwrite); 
 
   image.Dispose(); 
   codecs.Dispose(); 
       
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
