Class BarCodeConfidence

  • java.lang.Object
    • com.aspose.barcode.barcoderecognition.BarCodeConfidence


  • public final class BarCodeConfidence
    extends java.lang.Object

    Contains recognition confidence level


     This sample shows how BarCodeConfidence changed, depending on barcode type
     
     //Moderate confidence
     BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.CODE_128, "12345");
     generator.save("test.png");
     BarCodeReader reader = new BarCodeReader("test.png", DecodeType.CODE_39_STANDARD, DecodeType.CODE_128);
         for(BarCodeResult result : reader.readBarCodes())
         {
             System.out.println("BarCode Type: " + result.getCodeTypeName());
             System.out.println("BarCode CodeText: " + result.getCodeText());
             System.out.println("BarCode Confidence: " + result.getConfidence());
             System.out.println("BarCode ReadingQuality: " + result.getReadingQuality());
         }
     //Strong confidence
     BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.QR, "12345");
     generator.save("test.png");
     BarCodeReader reader = new BarCodeReader("test.png", DecodeType.CODE_39_STANDARD, DecodeType.QR);
         for(BarCodeResult result : reader.readBarCodes())
         {
             System.out.println("BarCode Type: " + result.getCodeTypeName());
             System.out.println("BarCode CodeText: " + result.getCodeText());
             System.out.println("BarCode Confidence: " + result.getConfidence());
             System.out.println("BarCode ReadingQuality: " + result.getReadingQuality());
         }
     
    • Field Summary

      Fields 
      Modifier and Type Field and Description
      static int MODERATE
      Recognition confidence of barcode (mostly 1D barcodes) with weak checksumm or even without it.
      static int NONE
      Recognition confidence of barcode where codetext was not recognized correctly or barcode was detected as posible fake
      static int STRONG
      Recognition confidence which was confirmed with BCH codes like Reed–Solomon.
