说明：  c++一个类实现小波分解重构,采用卷积抽稀,很好的一个源代码,注释也很清楚,我也是从最基本的原理写起,希望可以给那些刚刚想编小波变换的人一点帮助
(c++ a class to achieve reconstruction of wavelet decomposition, using convolution pumped thin, a very good source code, comments are also very clear that I am also from the most basic tenets of writing, the hope for those who just want to made Wavelet Transform people that help)
