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, "TextBlurBarcode.jpg")); 
 
   //Prepare the command 
   TextBlurDetectorCommand command = new TextBlurDetectorCommand(); 
 
   //Apply  
   command.Run(image); 
 
   //Result 
   Debug.WriteLine(command.InFocusBlocks.Length   );  //Number of blocks 
   Debug.WriteLine(command.OutOfFocusBlocks.Length);  //Number of blocks 
   Debug.WriteLine(command.CombinedTextBlocks.Left);  //represents the left boundary of all in focus blocks 
}
