我有一个大小为2000乘4059的modis tiff 图片,其值为int16。我希望将图像乘以比例因子0.0001以获得Matlab中的反射率。

答案 0 :(得分:0)

正如@zplesivcak所说:

 img = imread( 'myModisImg.tiff' ); %// img should be 2000x4059 array of type uint16
 img = im2double( img ); %// now img is of type double in the range [0..1]
 rimg = img * 0.0001; %// multiply each pixel by 0.0001
