1)  Logarithmic error criterion
对数误差准则
2)  relative error criteria
相对误差准则
3)  error norm function
误差准则函数
1.
It defines an error norm function for different DCT coefficients to dynamically choose the embedding position,and adaptively embed watermark of different strength according to the degree of modification.
此外,提出了一种量化误差补偿机制,它对不同的DCT系数定义了一个误差准则函数,根据该函数的值动态地选择水印的嵌入位置,并根据视频的修改程度,自适应地嵌入不同强度的水印,仿真实验结果表明,该算法能快速地嵌入和提取水印信息,水印嵌入容量较大,且嵌入补偿机制有效降低了量化和水印引起的误差。

补充资料:相对误差
分子式:
CAS号:

性质:误差与被测量的真值之比。以百分率表示,所以又称百分误差(percentage error)。仪表的相对误差有两种表示方法:(1)实际相对误差,为绝对误差与被测量的实际值(约定真值)之比;(2)标称相对误差,为绝对误差与仪表标称值(示值)之比。
