How to write or save sequence of images in a folder using opencv?

I am trying to like this

imwrite( "/home/administrator/Desktop/bg_sub/%d.jpg", image );

but it is storing only one image. Please tell me what should I do now

Well that is because the imwrite function does not know on its own what he has to place at the %d counter. The suggestion of @thdrksdfthmn is indeed better and more stable.

Your approach is good, but you I would suggest you a little modification:

int cntr = 0:

// ...

// saving part:
std::string savingName = "/home/administrator/Desktop/bg_sub/" + std::to_string(++cntr) + ".jpg";
cv::imwrite(savingName, image);
