摘要
This paper deals with 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. The validity of the method is validated by experimental results.
