我有一个大小为 2000 x 4059 的 modis tiff图像,带有int16值。我想将图像乘以 0.0001 的比例因子以获得 Matlab 中的反射率。
int16
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
