Summary

Gets the accuracy of the result, in hundredths of a percent.

Syntax

Objective-C

C++/CLI

Java

Python

public int Accuracy { get; }

@property (nonatomic, assign, readonly) NSUInteger accuracy;

public int getAccuracy();

public: 
property int Accuracy { 
   int get(); 
}

Accuracy # get  (BlankPageDetectorCommand)

Property Value

The accuracy of the result. Possible values range from 0 through 10000. This value is divided internally by 100.

Example

Runs the BlankPageDetectorCommand on an image and determines whether it is blank.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void BlankPageDetectorCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Clean.tif")); 
 
   // Prepare the command 
   BlankPageDetectorCommand command = new BlankPageDetectorCommand() 
   { 
      // The following properties can be left to their defaults or set to desired values: 
      LeftMargin = 0, 
      TopMargin = 0, 
      RightMargin = 0, 
      BottomMargin = 0, 
      MinimumTextSize = 0 
   }; 
 
   //Determine whether the image is a blank page 
   command.Flags = BlankPageDetectorCommandFlags.DetectNoisyPage; 
   command.Run(image); 
 
   MessageBox.Show(" Is Blank   : " + command.IsBlank + "\n Accuracy : " + (command.Accuracy * 1.0 / 100) + "%", "Blank Page Detection Results");
