ENCODING INFORMATION IN A GRAPHICAL ELEMENT OF AN IMAGE

摘要

In an example, a processor-readable medium stores code representing instructions that when executed by a processor cause the processor to receive an image, a graphical element, and embedding information. The processor further encodes a binary value representing the embedding information into the graphical element. The zeros and ones from the binary value are distinguished in the graphical element by a difference in luminance values applied to segments of the graphical element. The processor further combines the encoded graphical element with the image without altering the image.

1. A non-transitory processor-readable medium storing code representing instructions that when executed by a processor cause the processor to:
receive an image, a graphical element, and embedding information; partition the graphical element into segments to accommodate a binary numerical value that represents the embedding information; pre-determine locations along the graphical element for placement of binary values from the binary numerical value; and encode the binary numeric value into the graphical element as a plurality of data carrying segments, the segments comprising a plurality of different color-space values.
