Hi there, I know how to read and process a single image using Mat variables. Recently, I´ve a nightmare about arranging multiple images. For example, suppose I want to read a 5x5 array of RGB images and another 8x8 array of RGB images. Please keep in mind that the number of horizontal and vertical images are not known in advanced and they should be set on the run time. Should I define multiple Mat variables to store 5x5 or 8x8 RGB images? How can I access/modify each image? Thank you for your help.

either you did not read the answer here, or you did not understand it.

I used this page, but it sounds like the dimensions of the array should be known in advanced and it can't be changed on the run time.

ever hear of push_back() ?

seriously, you have to know your c++ (and how to use dynamic containers), before doing this.

imho, your question is entirely off-topic (it's about c++ in general, not about opencv at all)

int main(int argc, char **argv) { vector<Mat> images; for (int i=1; i<argc; i++) { Mat im = imread(argv[i]); if (im.empty()) continue; images.push_back(im); } cout << "read " << images.size() << " images." << endl; ... }
