Hi Slava,

I need:

- The code you are using to do OCR.
- The document processed.
- The result of the OCR with the old version.
- The result of the OCR on the same document using the latest release.


For information: We changed anything about OCR from previous version

Kind regards,

Loïc

Hi Loic,

These reports came from a customer that is using our Pre-Release application version which always includes the latest GdPicture ActiveX Toolkit. This customer processes hundreds of invoices where OCR functionality of your toolkit is used in different ways (full document OCR, area OCR, dictionary training, applying filters and scaling documents). I can send the code but it is complicated and will take time for preparations.

Why am I telling you all this - is that the information about OCR quality is statistical, over hundreds processed documents! That is basically all I know. For me to send the comparison of the OCR results will require re-building and re-testing both versions with own documents. I will do the best to reserve time for this at the end of next week. If I confirm the OCR quality decrease after the testing, I will send the required information to you.

Could you please reply on this topic in case you have more information on this before the end of next week?

Thank you,
Slava

Hi Slava,

I checked modifications from previous source code and I confirm: Nothing have been changed on OCR. I think your problem come from another issue.

Kind regards,

Hi Loic,

Thank you very much for confirmation. At least I can now report back to the customer with this information.

Kind regards,
