Abstract
A method for identifying a QR code in an image includes inputting an image, and using one or more computer processor to identify edges in the image; create an edge count image; label connected regions in the edge count image; create a candidate region list; for each individual candidate in the candidate region list: find regions that overlap with the region in the individual candidate; group regions that overlap into a group of overlapped regions; for each group: merge the overlapped regions into a merged region; add each merged region to the candidate region list to form a new candidate region list; and perform decoding of a QR code in each region in the new candidate region list.
