Recognize digits only

[ajmakoni]

Hello,
I like your work. How do I get it to recognize digits only. I intend to add it to my mobile that using Sencha Touch 2 that will be required to read digits from capture images such as business cards e.t.c
Awaiting your feedback

I would just filter out the recognized letters that aren't numbers.

How, specifically, would you do that? I'm fairly new to this, and sifting through 1MB of code to find that specific line of code; it would take me ages!

You could take the output and then pass it through a regex `.replace(/[^\d]/g, '')

It may be that I have misunderstood the concept, but I thought that reducing the number of characters ocrad could recognize would make it more accurate. As of now, whenever I write "3", I end up with "j", "J", "_" or another character as often as "3", "1" produces "I", "6" produces "b" etc. If there was no "j", "J" og "b" in the "baseline", ocrad would not mix it up as often?

And it may be that I misunderstand what you mean on using regex.replace on the output. Do you mean ie. to manually replace all instances of "j", "J" with "3" and all instances of "b" with 6, and so on? Wouldn't reducing ocrad.js (in some way) be more effective programming?

All I (initially) want it to detect is "1234567890". Later I may want to expand to "+-*/:".

Is it possible to strip ocrad down like this in an easy way?

I've updated it to Ocrad 0.24 and built the javascript bindings for applying filters and other things. Look at examples/browser/numbers.html for how to restrict it to numeric recognition.
