BlurDetectionCommand Class

Summary

Determines whether an image is blurred.

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

Remarks
  • This command takes an image and determines whether it is blurred. If it is blurred it calculates the amount of blurring.
  • This command supports 8-bit, 12-bit, and 16-bit grayscale images and 24-bit and 32-bit colored images.

Example
C#
VB
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
using Leadtools.ImageProcessing.Effects; 
 
public void BlurDetectionCommandExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   //Load an image 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "cannon.jpg")); 
 
   //Prepare the command 
   BlurDetectionCommand command = new BlurDetectionCommand(); 
 
   //Apply  
   command.Run(image); 
 
   //Result 
   //command.Blurred equals false 
 
   //Apply Gaussian Blur to the image 
   GaussianCommand gcommand = new GaussianCommand(); 
   gcommand.Radius = 20; 
   gcommand.Run(image); 
 
   //Apply BlurDetection command again 
   command.Run(image); 
 
   //Result 
   //command.Blurred equals true 
   //command.BlurExtent equals 0.8745 
 
}
