A novel watermarking method based on watermark preprocessing in wavelet domain

摘要

This paper mainly comes up with a new watermarking arithmetic about the wavelet domain based on the pretreatment of the watermark. Through the pretreatment of watermark, it can greatly reduce the embedding capacity of the watermark, or we can say it greatly enhance the embedding capacity of the watermark under the same visual effect, which can embed more watermark in the host image. In the process of embedding, to embed the much stronger wavelet transform domain of the robustness, and lead in random embedding method, which greatly enhance the safety performance. The experimental result shows that this new arithmetic has an excellent transparency and robustness.
