Remarks

This command takes an image and divides it into many blocks, and then examines each block to determine if it is background and if it is in-focus or out-of-focus.
This command supports 8,12, 16-bit grayscale images and 24, 32-bit colored images.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void TextBlurDetectorCommandExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   //Load an image 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Barcode.jpg")); 
 
   //Prepare the command 
   TextBlurDetectorCommand command = new TextBlurDetectorCommand(); 
 
   //Apply  
   command.Run(image); 
 
   //Result 
   //command.InFocusBlocks contains 6 blocks 
   //command.OutOfFocusBlocks contains 2 blocks 
   //command.CombinedTextBlocks represents the boundary of all in focus blocks 
}

{ 
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images";
