New robust watermarking algorithm for vector data


Because the existing vector data watermarking algorithm is insufficiently robust for compression and cropping, and has no sufficient control on map deformation, a new watermarking algorithm was proposed in this paper. Its main features are: ➀ it selected feature points and non-feature points from the sequence of Douglas, and then embedded watermarking… (More)
