摘要

这项工作的目的是设计一种基于线性预测编码方法和MPEG-I标准中定义的心理声学模型的新型音频水印技术。利用频率掩蔽效应实现了嵌入的不可见性。感知音频质量的评估是通过标准化的ITU-R BS.1387质量评估方法进行的。在存在攻击的情况下,验证了该方法的有效性。

Perceptual audio watermarking driven by human auditory system
The aim of this work is the design of a novel audio watermarking technique based on the Linear Predictive Coding approach and on the psychoacoustic model defined in the MPEG-I standard. The embedding imperceptibility is achieved by exploiting the frequency masking effect. The evaluation of the perceived audio quality is performed by means of the standardized ITU-R BS.1387 quality assessment method. The effectiveness of the proposed method is tested in presence of attacks.
