Background: QRCode demo works well, so long that the QR code is big enough. However, i'm in a situation where my 2D barcode should resist well to occlusion + end up with a small size.
I read here and there, that using DATA_MATRIX format would likely be a better pick than QR code then.
However, zbar does not seem to support DATA_MATRIX format.
Google suggested 3 options (in no particular order)
Ideally, I would make a python poc, then look how well those barcodes behave compared to qrcodes in this specific application. Then improve performance by going cpp if required.
What would you suggest?
