A Perceptually Adaptive QIM Scheme for Efficient Watermark Synchronization

摘要

This study presents an adaptive quantization index modulation scheme applicable on a small audio segment, which in turn allows the watermarking technique to withstand time-shifting and cropping attacks. The exploitation of auditory masking further ensures the robustness and im-perceptibility of the embedded watermark. Experimental results confirmed the efficacy of this scheme against common signal processing attacks.
