Abstract |
|
Watermarking technique used in areas of text, image, audio and video for the purpose of copyright protection, broadcast monitoring, data authentication and identification of owner of multimedia documents in network environments. This paper informs about multiple transforms of watermarking technique DFT(Discrete Fourier Transform), DCT (Discrete Cosine Transform), DWT (Discrete Wavelet Transform), SVD (Singular value decomposition) and compare to each other based on its application. This paper also explain, false position problem in SVD and Rounding error problem which presently exists in the frequency domain with their solutions. |
