    说明:   这是一个用小波神经网络进行非线性函数逼近的例子,拟合效果非常好,保证能运行!有详细注释!我是参考《青岛海洋大学学报》 2001年第1期 一种基于BP算法学习的小波神经网络编写的,大家可以针对原文更好的理解我的程序!(This is a wavelet neural network with nonlinear function approximation example of fitting results is very good, guaranteed to run! Detailed Notes! I refer to Journal of Ocean University of Qingdao,2001 ,“a learning algorithm based on BP wavelet neural network ”, you will understand me better for program!)

    利用小波变换,通过设置阈值对图像进行去噪。 首先对图像用小波进行2层分解,然后通过设置硬阈值和软阈值的方法,对图像高频部分去噪。(The wavelet transform is used to denoise the image by setting threshold. Firstly, the image is decomposed into 2 layers by wavelet, and then the high frequency part of the image is denoised by setting the hard threshold and the soft threshold.)
