We have tried to recognize the sample barcodes shared by you using the latest version of the API i.e. Aspose.BarCode for Java 18.4. All the barcodes were recognized successfully except one i.e. ‘Bar Code Image 5.PNG’. If we look at this particular barcode image, it has a very large amount of distortion/noise in it. It is nearly impossible to recognize such kind of barcodes. We have attached the ouput for your reference.
Following is the sample code snippet used:
com.aspose.barcode.barcoderecognition.BarCodeReader reader = new com.aspose.barcode.barcoderecognition.BarCodeReader("Bar Code Image 1.PNG");
System.out.println(" codetext: " + reader.getCodeText());
Regarding using any other barcode type instead of QR barcode, you may use any another barcode type but the issue will remain as it is. Because the issue is related to quality of barcode image.
