Abstract

A blind method for watermarking of vector graphics images through polygonal line modification is proposed. The watermark is embedded in the Fourier descriptors of the polygonal lines, causing invisible distortions to the vertices coordinates. The properties of the Fourier descriptors ensure that watermarks generated by this technique withstand rotation, translation, scaling, reflection, change of traversal starting point/direction and smoothing
