int id = 0
The decoded ID of the tag
-
int hamming = 0
How many error bits were corrected? Note: accepting large numbers of corrected errors leads to greatly increased false positive rates. As of this implementation, the detector cannot detect tags with a hamming distance greater than 2.
-
float decisionMargin = 0.f
A measure of the quality of the binary decoding process; the average difference between the intensity of a data bit versus the decision threshold. Higher numbers roughly indicate better decodes. This is a reasonable measure of detection accuracy only for very small tags— not effective for larger tags (where we could have sampled anywhere within a bit cell and still gotten a good detection.
