Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A system, comprising: a memory to store computer-executable instructions; and a processor that executes or facilitates execution of the computer-executable instructions to at least: encode a message within a two dimensional barcode; embed a gray scale image into the two dimensional barcode to form a watermarked barcode via a watermarking that employs at least two tiling patterns; and add a finder pattern with markings at all four corners of the finder…
