Texture Classification Based Digital Watermarking Algorithmin Finite Ridgelet Transform Domain

摘要

This paper proposes a watermarking technique based on texture classification for image in finite ridgelet transform domain.The texture classification for image is accomplished by using the ridgelet transform.Significant sub-blocks of the images are determined according to the texture classification automatically.Watermarks are inserted in locations which are identified by ridgelet coefficients corresponding to the strong image texture.Experiments show that the proposed method can achieve a better tradeoff between the robustness and invisibility.
