I am trying to read a sequence of files from a folder. I am using glob but the problem is that it is not reading 1, 2, 3, 4 etc. It is reading 1, 101, 102... 108, 11, 111, 112....

Can someone help me fix this please

if your files are really numbered consecutively (and if those are in fact images), you could try via VideoCapture, like:

VideoCapture cap("file%d.png"); // think printf()
while(1) {
      Mat im;
      if (!

in the long run, if you want your files to be lexically ordered, you have to take care to get the names right, like file00001.png and file2016-03-24.jpg

Hello thanks ! I made sure the format of the numbers were in the form 0001 instead of 1
