Robust Watermarking of Cartographic Images
We present a method (Text-Based Geometric Normalization—TBGN) which, by exploiting the particular content of cartographic images, namely text content, permits to cope with global geometric transformations. First, text is extracted from the to-be-marked map, then text orientation and size are ex...
