An improved wavelet digital watermarking software implementation

There are quite a number of researches in propOSll1g digital image watermarking using Discrete Wavelet Transform (DWT). However, it is clearly observed that each of them is individually distinctive in terms of its scopes and applications [1][2][3]. The proposed system was thoroughly explained in th...
