二维小波包分解在计算机图像重构中的应用

摘要

Wavelet decomposition is widely used in signal processing, in the computer image signal processing, image reconstruction technology is more critical, wavelet packet decomposition can be divided into various frequency bands and image signals, this paper describes the image processing, wavelet decomposition, wavelet packet decomposition, and the application of MATLAB software on the application of two-dimensional wavelet packet decomposition of image signal reconstruction for computer simulation, simulation results show that the method has a better signal processing effect.%小波分解广泛应用于信号处理，在计算机图像信号处理中，图像重构技术较为关键，小波包分解可对图像信号各个频段进行及其细化的划分。文中分别对图像处理，小波分解，小波包分解进行阐述，并应用MATLAB对二维小波包分解对图像信号重构进行仿真。仿真结果表明，该方法具有较好的信号处理效果。
