信息隐藏技术在气象图片传输中的应用研究

卫星云图给天气预报提供了重要的信息,在国民经济中具有举足轻重的作用,一旦图片传输有误,将会带来不可估量的损失。信息隐藏随着计算机技术和网络的飞速发展越来越引起人们的关注,其作用也日趋明显。将信息隐藏技术应用于图片传输中,就可以加以避免。该文简单概述了信息隐藏技术的含义和特征,具体介绍并实现了基于DCT域彩色图像的信息隐藏技术。实验结果表明,该方法是可行的。

Research on the picture transmission by Information Hiding technology

People payed more and more attention with the fast increasing of Information Hiding technology and network.This paper summarised the definition and characteristic of Information Hiding simply and performed the Information Hiding based on DCT. The feasibility of this proposed method was proved by experimental results.
