摘要
对基于心理声学模型的音频水印算法的能量与相关检测可靠性的关系进行了分析研究。给出计算音频水印相关检测的检测阈值的方法,并描述了水印能量、检测阈值以及信噪比与检测误码率的关系。实验结果验证了水印检测错误率随着水印能量的增加而降低,随着信噪比的增大而增加。
This paper analyzes the energy and reliability of audio watermarking algorithm based on psychoacoustic model. It presents the method of detection threshold of watermark correlation detection, and describes the connection of the watermark energy, detection threshold, and SNR with the detection error. The experimental results show that watermarking detection error decreases with the increase of watermarking energy and SNR.
