title: QRCode Extraction With ZXing
body: <p>Hi I'm trying to read QRCode from scanned images, but I'm getting a low index of extraction (19 extracted from 500 images) the code of extraction:</p>
  
  <pre><code>class QrExtractor
  {
      public String extractFrom(Bitmap image)
      {
          using (image)
          {
              LuminanceSource source;
              source = new BitmapLuminanceSource(image);
              BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source));
              Result result = new QRCodeReader().decode(bitmap);
              if (result != null)
              {
                  return result.Text;
              }
              return "Couldn't Extract";
          }
      }
  }
  </code></pre>
  
  <p>Is there any improvements that I can apply to this?</p>
  
  <p>Thanks</p>
