Abstract: A method is provided for delivering information content relating to an object. A first image of a pattern on the object is received. An outer border of the first image is detected, and a second image framed by the outer border is located. The second image is decoded to determine a digital identifier. Information content relating to the digital identifier is delivered.

Abstract: A method is provided for decoding an image of a pattern on an object to determine a digital identifier. An image of a pattern on the object is received. The image includes a plurality of pixels, each of the pixels having an optical attribute with a corresponding value. The image is divided into a plurality of tiles, each of the tiles containing a contiguous plurality of the pixels of the image. A digital bit is assigned to each of the tiles based on the values of the optical attribute of the pixels in the tile. A digital identifier is determined based on the digital bits assigned to the tiles.
