Signal rich art is an application of watermarking technology to communicate information using visible artistic patterns. In this paper we show new methods of generating signal carrying patterns, simplifications of earlier methods, how to embed a vector watermark signal in applications and how to use signal symmetries to expand the detection envelope of a watermark reader.
Digital watermarking technologies are based on the idea of embedding a data-carrying signal in a semi covert manner in a given host image. Here we describe a new approach in which we render the signal itself as an explicit artistic pattern, thereby hiding the signal in plain sight. This pattern may be used as is, or as a texture layer in another image for various applications. There is an immense variety of signal carrying patterns and we present several examples. We also present some results on the detection robustness of these patterns.
