Abstract
In this paper, the effect of binary labelling bins for lattice quantization index modulation techniques is studied. The problem can be solved in one dimension using Gray codes but it is not straightforward for higher dimensions due to more directionality. We show the impact of different labellings on the overall performance of two-dimensional lattice quantization index modulation watermarking systems. Heuristically, we present solutions for these systems, where our analysis includes (1) robustness tests against JPEG and JPEG 2000 compression and (2) transmission over an AWGN channel.
