Most quantizer based data hiding schemes use uniform quantizer, which is not optimal if the host signal is not uniformly distributed. In this paper, we design a quantizer that is ...

A particular application of audio data hiding systems and watermarking systems consists of using the audio signal as a transmission channel for binary information. The system shou...
