Hello

I am trying to convert an image to a binary file (not binary image) for further processing in another software. I have tried the following code but does not seems to work as the file I am creating is zero bytes !

I= imread('cameraman.bin','w')
    fid=fopen ('cameraman.bin','w');
      fwrite(fid,I,'float32');

Can someone advice me on how to do this correctly ?

Thank you

As far as I know there is no defined format for .bin. It's like .raw - you can basically define it however you want. You need to find out what format that other software package wants.

在 MATLAB Online 中打开

Try this out:

I= imread('cameraman.tif');
level = .5;
BW = im2bw(I, level);
%choose your own options when writing to txt file
dlmwrite('myfile.txt', BW)
dlmwrite('myfile.txt', BW, 'delimiter', '\t', 'precision', 6)
