说明：  双边去噪的matlab源码，效果很好，值得一试(Bilateral denoising matlab source, the effect is very good, worth a try)

人工加入椒盐噪声，进行中值滤波去噪,可以自己加入不同密度的椒盐(Artificial adding salt and pepper noise, median filtering denoising, you can add your own salt and pepper different densities)

说明：  对近红外光谱进行多元散射校正的源代码，需要另建函数进行调用。另外一个是Kennard-Stone算法用于划分训练集和验证集。(The source code for multi-scattering correction of near infrared spectroscopy needs to be invoked by another function.Another is the Kennard-Stone algorithm, which is used to divide training set and verification set.)

应用背景The MNIST database of handwritten digits, available from this page, has a training set of 60,000 examples, and a test set of 10,000 examples. It is a subset of a larger set available from NIST. The digits have been size-normalized and centered in a fixed-size image. It is a good database for people who want to try learning techniques and pattern recognition methods on real-world data while spending minimal efforts on preprocessing and formatting. 关键技术The MNIST database was constructed from NIST"s Special Database 3 and Special Database 1 which contain binary images of handwritten digits. NIST originally designated SD-3 as their training set and SD-1 as their test set. However, SD-3 is much
