说明：  my_noise文件是已知信号方差，加入信号噪声，可以加入高斯噪声，淑盐噪声,等其他噪声十分有用 其他两个函数时加入噪声信噪比SNR,但是有一点,这种方法并不准确,不能保证加入噪声信噪比为SNR,实际测试中可以看出,但是可以加入相同的信噪比的噪声(my_noise document is known to signal variance, by adding signal noise, Gaussian noise can be added, suk salt noise, noise, and other very useful function when the other two noise signal to noise ratio SNR, but there is one point, this method is not accurate , can not be guaranteed by adding the noise signal to noise ratio for the SNR, the actual test can be seen, but can join the same noise signal to noise ratio)

JPEG压缩方法由于其较高的压缩比和理想的压缩效果，是目前应用最广泛的图像压缩方法(JPEG compression method because of its higher compression ratio and ideal compression effect, is currently the most widely used method of image compression)

在我们的移动端开发中，需要用到折线图，本篇内容就是用flutter写的一个折线图例程。(In the development of our mobile terminal, we need to use the line chart. This article is a line chart routine written by flutter.)

说明：  运用小波变换将图像从空间域转换到频率域，自己写的代码，欢迎讨论学习(Using wavelet transform to transform image from spatial domain to frequency domain)

用spiht写的图像压缩代码，适用于基于DWT的图像压缩，欢迎下载(Written by SPIHT image compression code, the application of DWT-based image compression, welcome to download)

图像缩放,在readme.txt里有详细的使用说明(image zoom, the readme.txt are detailed usage)
