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); endNow 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.txtNote 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); endwhere each integer is padded with up to three zeros, then I get the correct ordering of the files as
