Abstract
The present disclosure relates to systems and methods for decoding intrinsic matrixed bar codes, such as Quick Response (“QR”) codes. In one implementation, system for decoding an intrinsic matrixed bar code may include an image-receiving device, a processor configured to execute instructions, and a memory storing the instructions. The instructions may include instructions to: receive an image using the image-receiving device; determine whether the received image contains at least one registration mark; when the received image is determined to have at least one registration mark: determine, from the at least one registration mark, one or more coordinates; when the received image is determined not to have at least one registration mark: determine one or more coordinates based on a detected color shifting of a portion of the image; and extract one or more matrixed bar codes overlaid on the received image and located at the one or more coordinates.
