MATLAB: Processing tiff file in matlab and save it again as tiff file

Question

I have a tiff satellite image ı want to make some calculations with it and ı want to save it as a tiff file again how can I do this ?

Answer 1

There is more than one way that you can save multiple images in a .tif . The following code works with one of the common ways:

in_filename = '200301.tif';
imgcount = 0;
saved_images = {};
while true
  nextimg = imgcount + 1;
  try
    t = imread(in_filename, 'Index', nextimg);
    imgcount = nextimg;
    saved_images{imgcount} = t;
  catch
    break;   %end of tiff
  end
end

Now manipulate the contents that are in the cell array saved_images, producing new_images

Afterwards,

out_filename = '200301_processed.tif';
imwrite(new_images{1}, out_filename);
for K = 2 : length(new_images)
  imwrite(new_images{K}, out_filename, 'WriteMode', 'append');
end
