Hi, I am working on image processing for my thesis and I need process hundreds of images at one time, so I would like to know whether I can store these image mat in one data structure, like cell in matlab, then I can get something like the following:

Cell all_images = cell(1,numofImage); for (int i = 0; i < numofImage；i++){ Mat img = imread( image(i) ) all_images(i) = img; }

Or does there exists some other ways for me to store several images at one time? By the way, I am using VS2013 with C++. Does anyone who has some idea about it? Thanks! ^0^

use a std::vector for this:

std::vector<cv::String> filenames;
cv::glob("/my/images/*.png", filenames); //all png files in that folder

std::vector<cv::Mat> images(filenames.size());
for (size_t i=0; i<filenames.size(); i++) {
    images[i] = cv::imread(filenames[i]);
}
