Hi Chris,
You can use the following code to save the image in the .tiff format without scaling. The code snippet uses the MATLAB’s Tiff object, you can refer https://www.mathworks.com/help/matlab/ref/tiff.html for more details.
% filename: the name with which you want to save the file
% image: 240*200 double matrix with range 0-1
t = Tiff(filename, 'w');
tagstruct.ImageLength = size(image, 1);
tagstruct.ImageWidth = size(image, 2);
tagstruct.Photometric = Tiff.Photometric.MinIsBlack;
tagstruct.BitsPerSample = 64; % 64-bit floating-point
tagstruct.SamplesPerPixel = 1;
tagstruct.PlanarConfiguration = Tiff.PlanarConfiguration.Chunky;
tagstruct.SampleFormat = Tiff.SampleFormat.IEEEFP;
tagstruct.Compression = Tiff.Compression.None;
t.setTag(tagstruct);
t.write(image);
t.close();
I hope this helps.
