摘要
简述了对回声隐藏技术的最初设想、心理声学原理及最基本的回声隐藏方法,在此基础上总结了回声隐藏算法的研究进展情况,主要归纳了对回声核的改造,同时对各种回声核结构进行了模拟仿真测试,通过测试结果分析并比较了各方法的优缺点,展望了回声隐藏技术领域的研究发展方向。
First,initial assumes of echo hiding,psycho-acoustic principles and original methods of echo hiding are introduced,and then the recent advances in research on echo hiding technology over the past 10 years since it appearance is summarized. The improvement of echo kernel and the advantages and disadvantages of various methods are analyzed and compared. Finally,some hot issues and the prospect of the development are forecasted.
