摘要：

Most. quantizer based data hiding schemes Use uniform quantizer, which is not optimal if the host signal is riot uniformly, distributed. In this paper, we design a quantizer that is not only. pdf-matched but also more suited to embedding than the Linde-Buzo-Gray (Lloyd-Max) algorithm for vector (scalar) quantizer design. Experimental results shows that the proposed scheme provides better trade-offs between robustness to attacks, embedding induced distortion and embedding capacity than a simple pdf-matched scheme. The proposed algorithm also shows about 3dB improvements in embedding distortion over other Popular quantizer based embedding algorithms.
