Description
The quality of the barcode recognition needs to be improved.
If this is not possible, it is necessary to integrate an external service (cloud) that can guarantee a higher success rate

they are all B/W scans and this gives the notorious salt & pepper problem. For better result, scan with 256 shared of gray.
It's quite hard to find where the barcodes are in your scans, so to improve the recognition rate we have to introduce the capability to define zones like we already done for the ZonalOCR: with zones we can then reliably read those barcodes

This online barcode reader is able to recognize all the bcode documents I tested so far

other commercial online tools were unable to recognize those barcodes, not really the best quality scans to consider.
Inliteresearch is able to detect those barcodes because it executes more and elaborate different quadrants of the image, in other words it tries do define zones and then each zone is processed independently, inf the barcode falls in a quadrant then it is able to recognize it even if the scan is poor quality.
The zonal recognition is the key for really improving the reliability, then we can also connect with Inliteresearch if the user can afford the purchase of the subscription and also our development efforts.

Pleas attach a couple of files that LogicalDOC was not able to recognize so we can execute tests among different technologies.
