Lifting scheme based non-blind hybrid image watermarking technique using low frequency band

Here in the paper, we proposed lifting scheme based non-blind hybrid image watermarking technique by utilizing low frequency band for hiding message. In proposed work, we change the singular values of the cover image with the help of embedding formula to achieve high robustness and transparency. Here, watermark is embedded into the low frequency sub-band of a cover image by using variable scaling factor. This technique is simple as compared to other in term of both insertion and extraction of the watermark in the cover image. The simulated results show the importance of proposed image watermarking scheme. This technique also tested with HVS and with the help of parameters namely peak signal noise ratio (PSNR) and normalized cross correlation (NCC).
