Abstract
The present disclosure relates to systems and methods for decoding 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; at least one processor configured to execute instructions; and at least one memory storing the instructions. The instructions may be to perform operations including receiving an image using the image-receiving device; determining a grid for the image, the grid having a plurality of cells; selecting at least one cell of the grid as a candidate cell for containing an intrinsic matrixed bar code; extracting at least one intrinsic matrixed bar code located within the candidate cell; determining that the at least one extracted matrixed bar code is degraded; and repairing the at least one extracted matrixed bar code.
