I didn't mention anything about accuracy, I said that it would be simpler to implement, which might or might not be correlated with accuracy. However in this case, we see a scenario where OCR would be more accurate indeed. So just reread the article and you might understand how OCR can be more accurate. It's because in case of disparity between the printed optical 2D matrix and some interpretation of the text/print encoding, the optical matrix is correct. PDF is a printing encoding, not a machine consumption, there's thousands of ways to print a document, it's not feasible or practical to understand all of them to build a document parser, you need to focus on the end result, not the process, like we do when analyzing a document. If you are analyzing the Mona Lisa, maybe it's useful to understand how it was painted. But if you are analyzing your electricity bill, it's likely that going into what order the numbers were printed and what ink was used, is going to be more of a distraction than anything useful. >Another thing to consider is OCR works well for English but not so well for other languages. Maybe, not terribly in scope for the case in the OP, as long as arabic numerals are used, that's the core of the requirements.
