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
