In the paper,the typical and commonly used pre- treatment methods are described and compared the advantage with the disadvantage of smoothing,multiplicaive seater correction(MSC) and standard normal variate correction(SNV).
重点分析平滑处理(smoothing)、多元散射校正(MSC)、标准正态变量校正(SNV)等常用光谱预处理方法的利弊,详细介绍小波变换(WT)、正交信号校正(OSC)等新光谱预处理方法。
