A New Watermarking Method Based on Analytical Clifford Fourier Mellin Transform

Abstract : we propose a new watermarking method based on Harris interest points and Fourier Clifford Transform. We employed Harris detector to select robust interest points and to generate some non-overlapped circular interest regions. Each region is transformed into Clifford Fourier domain and the watermark is embedded into the Clifford transform coefficients magnitude. Experimental results show the robustness of the proposed method against JPEG compression.
