Experiments
ReacTIVision
USB Camera 352 x 288 / 15fps used. reacTIVision for windows binary 1.4.
Basic recognition works quite well
Also partially hidden image is recognized
But sometimes even larger one is not
Smalest image recognized properly
In larger distance, image is too small to identify
QR code
Even the simpe QR code containg less than 10 ASCI letters is not recognized:
Could not find any barcode in the uploaded image.
