See LICENSE_FOR_EXAMPLE_PROGRAMS.txt -/* - - This example shows how to use the correlation_tracker from the dlib C++ library. This - object lets you track the position of an object as it moves from frame to frame in a - video sequence. To use it, you give the correlation_tracker the bounding box of the - object you want to track in the current video frame. Then it will identify the - location of the object in subsequent frames. - - In this particular example, we are going to run on the video sequence that comes with - dlib, which can be found in the examples/video_frames folder. This video shows a juice - box sitting on a table and someone is waving the camera around. The task is to track the - position of the juice box as the camera moves around. -*/ - -#include <dlib/image_processing.h> -#include <dlib/gui_widgets.h> -#include <dlib/image_io.h> -#include <dlib/dir_nav.h> - - -using namespace dlib; -using namespace std; - -int main(int argc, char** argv) try -{ - if (argc != 2) - { - cout << "Call this program like this: " << endl; - cout << "./video_tracking_ex ../video_frames" << endl; - return 1; - } - - // Get the list of video frames. - std::vector<file> files = get_files_in_directory_tree(argv[1], match_ending(".jpg")); - std::sort(files.begin(), files.end()); - if (files.size() == 0) - { - cout << "No images found in " << argv[1] << endl; - return 1; - } - - // Load the first frame. - array2d<unsigned char> img; - load_image(img, files[0]); - // Now create a tracker and start a track on the juice box.
