Digital Video Watermarking for Copyright Protection

Abstract: Today the world is so fast as the digital multimedia applications are increased. Spatial domain and transform domain can be divided in digital watermarking. The spatial domain method is the simple form of watermarking technique but it has lowest robustness against the attacks whereas the transform domains have highest robustness and are more complex. The important and most common methods of watermarking are DWT (discrete wavelet transform) and DCT (Discrete cosine transform). Our project is digital video watermarking scheme which is based on DWT (discrete wavelet transform) and PCA (principle component analysis). The PSNR (peak signal to noise ratio) plays most vital role which is used to calculate efficiency of all methods. And this value must increase upto level.

Keywords: DWT, DCT, PCA, PSNR, binary watermark.
