matlab 光谱数据基线校正

以下是两种Matlab光谱数据基线校正的方法:
1. 基于形态学运算(MOR)的基线校正方法
```matlab
% 导入光谱数据
data = importdata('spectra.txt');
% 获取光谱数据的行数和列数
[rows, cols] = size(data);
% 对每一列进行基线校正
for i = 1:cols
% 使用MOR算法进行基线校正
baseline = MOR(data(:,i), 10);
% 将基线校正后的光谱数据保存到新的矩阵中
corrected_data(:,i) = data(:,i) - baseline;
end
% 将基线校正后的光谱数据保存到文件中
dlmwrite('corrected_spectra.txt', corrected_data, 'delimiter', '\t');
```
2. 基于小窗口移动平均的基线校正方法
```matlab
% 导入光谱数据
data = importdata('spectra.txt');
% 获取光谱数据的行数和列数
[rows, cols] = size(data);
% 对每一列进行基线校正
for i = 1:cols
% 使用小窗口移动平均算法进行基线校正
baseline = smooth(data(:,i), 100, 'moving');
% 将基线校正后的光谱数据保存到新的矩阵中
corrected_data(:,i) = data(:,i) - baseline;
end
% 将基线校正后的光谱数据保存到文件中
dlmwrite('corrected_spectra.txt', corrected_data, 'delimiter', '\t');
```
