Estimation for filtering attacks on QIM watermarks
A scheme for estimating two-band amplitude scale attack within a quantization-based watermarking context was presented.Quantization-based watermarking schemes are not robust against linear time invariant（LTI） filtering attacks,on which a multi-band amplitude scaling attack that modifies the spectrum...
