Figure 8From: Efficient blind decoders for additive spread spectrum embedding based data hidingThe average bit error rate versus WNR for the ML, GML, and LMMSE decoders, where 4,096 bits of information are embedded in the magnitude of the DFT domain of each testing image. The modified SS and ISS embedding schemes are employed, respectively, and DWR = 30 dB.Back to article page
