Has anyone ever written or heard of a datamatrix code decoder written in OpenCV?
I have used the decoder that comes with ZXing, but to be honest, its pretty bad. It needs to be a fully clear image, using the entire image, and not at an angle. The latter being the biggest drawback for me. There are many apps out there that can read an image and recover from things like being blury, at an angle, or even only 40% of the image.
If anyone knows another SDK that would work better, please let me know. Ive used opencv many times, and it seems like it wouldn't be very hard to write a datamatrix decoder, I'm just surprised the code isnt out there.

It's actually embedded. Furthermore, if you state 'it wouldnt be too hard', and given the fact that you are looking for it and haven't found it, how about contribute yourselves? https://code.ros.org/trac/opencv/browser/trunk/opencv/modules/objdetect/src/datamatrix.cpp
