(#31)
Table 1 of the paper has a breakdown of bit accuracy for different camera / printer pairs - https://arxiv.org/abs/1904.05343
Yep, you are correct.

Hello, tancik!
Excuse me, if you don't use BCH code, what is the decoding accuracy (bit_acc)?
Every 12 bytes (96 bits), only 5 bits can be corrected, right?
encode_image.py
anddecode_image.py
, The BCH parameters you use are:bchlib
source code, my understanding is, The entire packet can only be corrected by 5 bits, right? In your case, packet is 12 bytes (96 bits), data is 7 bytes (56 bits, embedded link length)
