Hello,
I'm looking at Tesseract to underpin a commercial project I am
prototyping. My current plan is to interact with tesseract via the command
line from either a Python or Java running on a Beagleboard (small circuit
board with an ARM chip on it). For this purpose I'm pretty happy with
tesseract 3.10 prerelease - the fact that the lead developer has locked the
project and done a runner like a subprime victim is a bit of a problem (I'm
assuming that no emails from him means that he does not even monitor the
list any more).
From what I can see OCRopus is mainly targeted towards decoding whole
pages of text and is quite heavyweight - I need to read ID cards so
tesseract is a better prospect for me as it is lighter. Also I don't
necessary want to use Ubuntu and Python for this. The prospect of having to
hack an image up into a unsigned char * fills me with dread but I guess
someone else can do that between C++ and Java/Python/whatever.
I'd be perfectly willing to help out regarding Java (my main language)
focused stuff and trying to compile something to ARM as I need to do that
anyway. However my C++ knowledge is sketchy at best. I personally don't
care how many libraries the code depends upon as long as the instructions to
compile and include the external libraries are clear. I'd like to be able
to call directly from Java (or Python or ... both) but if not then a command
line program which I can shell and capture the results from is fine for me.
I'm not especially wedded to open source or tesseract - it is just that
tesseract was easy to get working and produced workable results. Does
anyone know of another project (proprietary or open source) which can do a
similar job?
Cheers,
Neil
