Abstract :
Through the in-depth analysis of the basic principles and existing research results of digital watermarking, drawing on the existing theory of the asymptotic grid, this paper presents a 2D vector graphics watermarking algorithm based on foundational contour. This algorithm by reducing the changes of the main body information and removing the extracted foundational contour in the transform domain embeds the watermarks, so as to achieve a more robust watermarking embedding effect.
