int main(int argc, char** argv){

    for ( indice=1 ;indice<=14; indice++ ){

        src = imread(cv::format("NouveauPermis/%d.jpg",indice).c_str(), indice);  


        // Pretraitement
        vector<Point> points = getMinMaxHistogram(src);
        calculLut(points[0],points[1], src);

        //imshow("l'image transformée",src);

        // Detection des contours
        contour = method_canny(src);
        //imshow("les contour",contour);

        imwrite(cv::format("NouveauPermisT/frame%d.jpg",indice).c_str(), src);

    return 0;

but i get this error when I run it:

You need to reduce this to the smallest possible code that throws the exception. What does reading 14 images have to do with anything? Where does "method_canny" come from?

the method I created it myself, what I want to do is read one image at a time(from a local forlder which contains 14 images)and then do a series of treats, I waste time reading the images one by one

check, if your images really were loaded (i bet, not so. it's the typical noob problem)
