A Reversible Watermarking Scheme for Vector Maps Based on Multilevel Histogram Modification
To protect the security of vector maps, we propose a novel reversible watermarking scheme for vector maps based on a multilevel histogram modification. First, a difference histogram is constructed using the correlations of adjacent coordinates, and the histogram is divided into continuous regions an...
