SRADAnisotropicDiffusionCommand Class

Summary

Applies a 2-Dimensional Anisotropic Diffusion filter on an image in order to reduce noise and speckling.

Syntax
C#
VB
Objective-C
C++
Java
public class SRADAnisotropicDiffusionCommand : RasterCommand 
Public Class SRADAnisotropicDiffusionCommand  
   Inherits RasterCommand 
@interface LTSRADAnisotropicDiffusionCommand : LTRasterCommand 
public class SRADAnisotropicDiffusionCommand extends RasterCommand 
public ref class SRADAnisotropicDiffusionCommand : public RasterCommand   

Remarks
  • The SRADAnisotropicDiffusionCommand (Speckle Reducing Anisotropic Diffusion) reduces noise and speckling in images while preserving the edges.
  • The number of iterations controls the number of times the filter will be applied to the image. The lower the number of iterations, the faster the filter will perform. Higher iterations typically mean clearer results.
  • This command processes only the entire image. It does not support regions.
  • This command supports 8, 16-bit grayscale images and 24, 32-bit colored images.
  • This command supports signed/unsigned images.

Example
C#
VB
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void SRADAnisotropicDiffusionCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE3.dcm")); 
 
   // Prepare the command 
   SRADAnisotropicDiffusionCommand command = new SRADAnisotropicDiffusionCommand(); 
 
   // Apply 
   command.Iterations = 10; 
   command.Lambda = 50; 
   command.Rect = new LeadRect(150, 300, 30, 30); 
   command.Run(image); 
}
