Improved Digital Image Watermarking Algorithm Based on Hybrid DWT-FFT and SVD Techniques


In proposed research, a novel and robust digital watermarking method is introduced in which a mixture of DWT (Discrete Wavelet Transform) and FFT (Fast Fourier Transform) along with SVD (Singular Value Decomposition) is applied. Due to the usage of this combination of three techniques in our proposed work, it increases the robustness and imperceptibility of extracted image. At first DWT-FFT-SVD techniques are applied for embedding the watermark then reverse algorithm is applied for extraction. The results are compared with Base Work1 in which single level DWT-SVD combination is taken for watermarking for copy right protection. It is shown through PSNR (Peak signal-to-noise ratio) that it provided a very high imperceptibility
