Watermarking Using the Local Relation of Wavelet Coefficient

In this paper, we proposed the digital watermarking algorithm in the transform domain. The main point of our algorithm is that the embedding system uses the relation of thresholds for watermark insertion. In the first, discrete wavelet transform is involved to calculate energy strength, and then we determined the range for watermark insertion by the priority of interrelation between threshold value of T₁, and T₂. The experimental results showed that proposed approach is relatively simply but robust against any such attacks.
