摘要
提出了一种基于提升小波变换的数字水印嵌入方案。提升算法是一种新的双正交小波构造方法,这种方法大大地降低了计算的复杂度,可有效地减少运行时间。详细地说明了提升算法的原理及实现步骤,并结合这种算法介绍了它在数字水印中的应用。
A digital watermarking embedded method based on lifting wavelet transform was presented. Lifting Scheme is a new method to construct biorthogonal wavelet, this method can decrease complexity of count greatly, and reduce runtime effectively. This paper explained the basic principle of lifting scheme in detail, and introduced applications in digital watermarking.
