MATLAB: Output file .txt

convertimage processingtext file

I have converted a .png image and each pixel to 16 bits and I want to save these bits in .txt file,but when I save my output file,my text file show the in each line the first bits and in the seconde line the seconde bits of the first pixel…..there is my code:

i want my file to be: in each line 16 bits

[sourcepic,phatsource]=uigetfile('*.png','C:\Users\hp\Desktop\images brutes LST\images brutes png\T4');
A=imread('C:\Users\hp\Desktop\images brutes LST\images brutes png\T4.png');
C=imresize(A,[695 316]);
d=reshape(C,[],1);
R=de2bi(d,16);
fid = fopen('C:\Users\hp\Desktop\ K.txt', 'wt');
fprintf(fid,'%o\n',R)

Make sure the folder containing the .png files is added to the MATLAB search path. You can use addpath to do the same.

Ali - how do you know that your images are in the correct order? For example, what does

 Files = dir('*.jpg');

return? I'm going to guess that your file names have a number in them, but you may not be getting the order that you expect. For example, the following loop creates a 100 (empty) text files

 for k=1:100
      fid = fopen(sprintf('test%d.txt',k),'wt');
      fclose(fid);
 end

Now when I do

 dir('test*.txt')

I observe that

               test18.txt   test28.txt   test38.txt   test48.txt   test58.txt   test68.txt   test78.txt   test88.txt   test98.txt   
  test1.txt    test19.txt   test29.txt   test39.txt   test49.txt   test59.txt   test69.txt   test79.txt   test89.txt   test99.txt   
  test10.txt   test2.txt    test3.txt    test4.txt    test5.txt    test6.txt    test7.txt    test8.txt    test9.txt    
  test100.txt  test20.txt   test30.txt   test40.txt   test50.txt   test60.txt   test70.txt   test80.txt   test90.txt   
  test11.txt   test21.txt   test31.txt   test41.txt   test51.txt   test61.txt   test71.txt   test81.txt   test91.txt   
  test12.txt   test22.txt   test32.txt   test42.txt   test52.txt   test62.txt   test72.txt   test82.txt   test92.txt   
  test13.txt   test23.txt   test33.txt   test43.txt   test53.txt   test63.txt   test73.txt   test83.txt   test93.txt   
  test14.txt   test24.txt   test34.txt   test44.txt   test54.txt   test64.txt   test74.txt   test84.txt   test94.txt   
  test15.txt   test25.txt   test35.txt   test45.txt   test55.txt   test65.txt   test75.txt   test85.txt   test95.txt   
  test16.txt   test26.txt   test36.txt   test46.txt   test56.txt   test66.txt   test76.txt   test86.txt   test96.txt   
  test17.txt   test27.txt   test37.txt   test47.txt   test57.txt   test67.txt   test77.txt   test87.txt   test97.txt

Note the ordering of the files: 1,10,100,11-19,2,20-29,3,30-39,etc. with early images being inserted every ten images. If your files are named in a similar fashion then you will need to force the correct order or rename he files. If, in the code above, I had named the files as

 for k=1:100
      fid = fopen(sprintf('test%03d.txt',k),'wt');
      fclose(fid);
 end

where each integer is padded with up to three zeros, then I get the correct ordering of the files as

dir('test*.txt')
