But errorproofness for swiss +payment slips is also quite relative: (a) the long reference digit +chains only have a very simple longitudinal 1-digit checksum that +catches many, but not all errors that happen if you key them in manually +and (b) all the OCR pograms that I have tested are far from perfect. And +yes, for some time I tried to use one of these portable devices - they +accumulate limited quality of scanning with limited quality of OCR +conversion: between handling and checking I spent more time than I need +for manual input and verification. + +My recent error scenario illustrates this: my incorrectly keyed in digit +string happened to not trigger a checksum error, hence was accepted by +the ebanking system of my bank, but was then rejected by the destination +bank because the string did not make sense to them. + +In the meantime, I have hacked a kind of tool which both shortens the +time I need to prepare my payments and diminuishes errorproneness, +- it selects the area to read and adjusts parameters for xsane, +- increases the output of xsane by a factor of 1.5 (amazing how that +reduces the errors of OCR conversion), +- submits the result to tesseract, +- does some string processing, +- displays the corrected and the original strings (see attachment - bad +quality to limit the size of this email), ready for copy paste. + +Looks very promising (and can be improved, I only spent half an +afternoon) - needs now to be assessed by really using it in +"production". Talking about generalisation - I see your arguments - does +only make sense once that provides positive results. + +Generalisation: maybe the concepts I put to work allow to create similar +tools / adjust the one I have made. I live part of my time in Austria - +Austrian slips should not be too difficult to handle along such lines. +And, maybe the mandatory introduction of IBAN input will create an +incentive to banks to improve the readability of their slips. + +Juergen +-------------- next part -------------- +A non-text attachment was scrubbed... +Name: convert.jpeg +Type: image/jpeg +Size: 14108 bytes +Desc: not available +URL: </pipermail/mageia-discuss/attachments/20130215/36752468/attachment-0001.jpeg> +</PRE> + + + + + + + + + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="009189.html">[Mageia-discuss] Reading payment forms with a scanner +</A></li> + <LI>Next message: <A HREF="009191.html">[Mageia-discuss] Reading payment forms with a scanner +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#9190">[ date ]</a> + <a href="thread.html#9190">[ thread ]</a> + <a href="subject.html#9190">[ subject ]</a> + <a href="author.html#9190">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-discuss">More information about the Mageia-discuss +mailing list</a><br> +</body></html> |
