摘要
Internet上的保密通信和数字产品版权保护方面的强烈需求,已成为信息隐藏技术研究的强大推动力.主要针对数字图像,探讨了人类视觉系统(HVS)在信息隐藏方面的应用.首先介绍了信息隐藏技术的基本模型与特性,接着述说了HVS的构成、特性以及图像质量评价方法.在此基础上,对空域法中的最不重要位(LSB)算法提出了改进并加以实现.
The intense demand of secure communication and copyright protection of the digital products on the Intcrnct have accelerated the development of information hiding technology. This article aiming at the digital image, has mainly discussed the Human Vision System （HVS） in the application of the information hiding aspects. The paper first introduces the basic model and its characteristics. Then, it recounts the HVS＇ constitution, characteristics and method of image quality value. On this basis, it improves and implements the Least Significant Bit （LSB） algorithm in the airspace law.
