• exponential hiding - 引用次数：2

  In the design part, we present a theoretical framework for digital watermark energy estimation based on energy conversation characteristic of unitary transforms, covering additive, multiplicative and exponential hiding methods.

  运用酉变换能量不变的性质，扩展提出了基于加性隐藏、乘性隐藏和指数隐藏方法的水印能量估计方法，建立了PSNR和嵌入强度的关系。
