Abstract:
A two dimensional barcode containing encoded information can be embedded with an image with a high visual quality. The encoded information within the barcode is meaningful to machines, while the image is meaningful to humans. The two dimensional barcode embedded with the image is designed such that machines can decode the information encoded within the two dimensional barcode even with the distortion from the image. The subject application describes various systems, methods and devices that can facilitate embedding the image within the two dimensional barcode, detecting the two dimensional barcode embedded with the image within a practical environment, and decoding the encoded information from the two dimensional barcode even with the distortion from the image.
