Digital Image Blind Watermarking Using DCT and DWT and Comparison on Both Techniques

Yash Kshirsagar; Vikas Gupta; Anshul Awasthi
The paper aims comparison of digital blind water marking technique using discrete cosine transform (DCT) and discrete wavelet transform (DWT). Both the methods are widely used among all the methods used for watermarking techniques like spatial domain techniques. Comparison between the two methods stated above has been done in terms of recovery time, Peak signal to noise ratio and NC. The simulation results show that DWT technique has faster recovery time and greater PSNR numerically. The comparison results are being shown at the end.
