Watermarking of sets of polygonal lines using fusion techniques
A blind watermarking method for the copyright protection of sets of polygonal lines in vector graphics images and GIS data (elevation contour maps) is presented. The paper focuses mainly on the use of simple fusion rules for combining the detector outputs from each polygonal line in order to come up with a global detection result. Experimental comparison of the various fusion methods using both synthetic and real data (elevation maps) is provided.
