摘要
小波变换是在傅里叶变换无法分析突变信号和非平稳信号的基础上产生的、具有多分辨率分析的时一频分析方法。它具有良好的时域和频域局部特性，因而在数据通信领域得到了广泛的领域。本文描述了小渡变换技术在图像压缩编码中的简单应用，并在MATLAB平台上进行仿真，实现了一级、二级两种扫描的图像压缩，突出了图像处理中采用小波变换技术的可行性和优越性。
Wavelet transform is developed on the basis of the short time fourier transform,it＇s a multi-resolution time-frequency analysis method.Because wavelet transform has excellent spatial-frequency characteristics in the time domain and frequency domain,it made great development and has been widely used in the area of data communication. This reading based on MATLAB platform and used wavelet transform,it realized images compression in the f＇trst and the second scans,and verified the feasibility and superiority of wavelet＇s using in image compression.
