How to get all images in folder using c++

Question

I have a problem. I'm writing C++ with the openCV library. I want to get the number of all images in a folder and I want to load all images in the folder for process in C++.

you can use glob to get a list of filenames:

vector<cv::String> fn;
glob("/home/images/*.png", fn, false);

vector<Mat> images;
size_t count = fn.size(); //number of png files in images folder
for (size_t i=0; i<count; i++)
    images.push_back(imread(fn[i]));
