Abstract
This disclosure relates to advanced signal processing technology including steganographic embedding and digital watermarking. One combination disclosed in the description is an image processing apparatus including: electronic memory for storing an image, in which the image comprises at least a 1D or 2D barcode represented therein and a first encoded signal encoded therein, the 1D or 2D barcode comprising a first plural-bit code and the first encoded signal comprising a second plural-bit code; means for decoding the 1D or 2D barcode from the image to obtain the first plural-bit code; means for analyzing data representing the image to obtain the second plural-bit code from the first encoded signal; means for determining whether the second plural-bit code conflicts with the first plural-bit code; and means for generating a conflict map, the conflict map comprising an identification of a code conflict, and a spatial location of the code conflict relative to the image. Of course, other features and combinations are described as well.
