摘要
在简单介绍小波原理的基础上,通过实例依次介绍低频信息保留压缩法、小波阈值压缩法和小波包全局阈值压缩法。由这三类方法并得出的图像压缩结果,得出各自的优缺点。所有实验均在MATLAB上用编程完成。
On the basis of introducing the principle of wavelet, several examples are showed orderly to illustrate the compression method of saving low frequency information, threshold of wavelet,and overall threshold of wavelet packet. From the results of compressing image by above method, the advantage and disadvantage of each method are got. All the experiments have been done on Matlab platform by programming.
