compilation in Ubuntu 14.04 about multitarget-tracker

[Smorodov]

Options USE_OCV_BGFG, USE_OCV_KCF, USE_OCV_UKF can be used only if you have installed opencv_contrib module, which is not installed by default. Else turn them off in cmake.

[Nuzhny007]

You can run cmake first. And then make.

[ARHLANE]

I tried to compile but I get the following error
arhlane@arhlane-HP-Pavilion-g6-Notebook-PC:~/Multitarget-tracker/build$ make -j3

[Nuzhny007]

Ok.
--std=gnu++14 used only for function std::make_unique. And gcc from 14.04 don't support this C++ standart.
What you can do: in CMakeLists.txt change to --std=gnu++11.
And all calls std::make_unique change to constructor std::unique_ptr.
See another ussue: #9

[ARHLANE]

Thank you very much for your reply
I made the changes you asked me
Now I have successfully executed the code but when I tried to compile the executable file (./MultitargetTracker) I receive the following error
OpenCV CNT algorithm is not implemented! Used Vibe by default.
OpenCV Error: Unsupported format or combination of formats in CvVideoWriter_GStreamer :: open, file /home/arhlane/opencv-3.1.0/modules/videoio/src/cap_gstreamer.cpp, line 1380

Aborted (core dumped)

[Nuzhny007]

OpenCV CNT algorithm is not implemented! Used Vibe by default.
This algorithm is new and absent in your OpenCV version. In main.cpp write:
CDetector detector(BackgroundSubtract::ALG_MOG, useLocalTracking, gray);

OpenCV Error: Unsupported format or combination of formats in CvVideoWriter_GStreamer
In main.cpp try write:
writer.open(outFile, cv::VideoWriter::fourcc('h', '2', '6', '4'), capture.get(cv::CAP_PROP_FPS), frame.size(), true);

[ARHLANE]

I replaced
CDetector detector (BackgroundSubtract :: ALG_CNT, useLocalTracking, gray);
by
CDetector detector (BackgroundSubtract :: ALG_MOG, useLocalTracking, gray);
And I also replaced
Writer.open (outFile, cv :: VideoWriter :: fourcc ('M', 'J', 'P', 'G'), capture.get (cv :: CAP_PROP_FPS), frame.size (), true);
by
Writer.open (outFile, cv :: VideoWriter :: fourcc ('h', '2', '6', '4'), capture.get (cv :: CAP_PROP_FPS), frame.size (), true); }

But I still receive the following error
OpenCV Error: Unsupported format or combination of formats (Gstreamer Opencv backend does not support this file type.)

[Nuzhny007]

Mmm... This error says that your version of gstreamer can't create result video file with mjpeg and h264 encoding. For check this hypotheses you can comment line Writer.open (outFile,

[ARHLANE]

when i comment line Writer.open..
Now I have successfully compiled the projects
Is that I can use it with ip camera?
Is that I can implement this projects with raspberry pi?
cordially

[Nuzhny007]

Yes, you can use this project with ip-camera. I don't know about gstreamer but on my Ubuntu OpenCV uses capture from ip-camera with ffmpeg. You can set address (eg std::string inFile("rtsp://admin:[email protected]/live");) and example will be work.

I haven't a Raspberry pi but Tracker must compile and work.

[ARHLANE]

I tried using an ip camera but it does not work in real time FPS too slow
Is that the problem is ffmpeg (already installed)?
cordially

[Nuzhny007]

You can use valgrind for profiling.
And more fast settings for detector and tracker:

bool useLocalTracking = false;
CDetector detector(BackgroundSubtract::ALG_MOG, useLocalTracking, gray);
CTracker tracker(useLocalTracking,
                     CTracker::RectsDist,
                     CTracker::KalmanLiner
                     CTracker::FilterCenter,
                     CTracker::TrackNone,      // Use KCF tracker for collisions resolving
                     CTracker::MatchHungrian,
                     0.3f,                    // Delta time for Kalman filter
                     0.1f,                    // Accel noise magnitude for Kalman filter
                     gray.cols / 20.0f,       // Distance threshold between two frames
                     fps,                     // Maximum allowed skipped frames
                     5 * fps                 // Maximum trace length
                     );

thanks for your reply
I use Valgrind for profiling and now the MotionDetector code works fine but I in my project I want the tracking and counting of the person, when I execute PedestrianDetector it does not work in real time FPS too slow even with a video
How can I improve tracking of people?
I have already done a person detection code with HOG now I need to add tracking in my code (Kalman for example) and that's why I tried to understand your implementation

[Nuzhny007]

Hi!
In our project uses c4-pedestrian-detector (example number 3 - function PedestrianDetector). From here: https://github.com/sturkmen72/C4-Real-time-pedestrian-detection
You can run our example - it will be faster then classic HOG detector.
And HOG detector also implemented - try it with macros #define USE_HOG 1

[ARHLANE]

Hello again
I tested the project C4-Real-time-pedestrian-detection but it is also very slow, is that the problem is the dimensions of vidio?
I do not know how I can get a real-time tracking (peaple) like your results (Motion Detection and Tracking: https://www.youtube.com/watch?v=GjN8jOy4kVw)

[Nuzhny007]

Hi!
In this video I don't use Pedestrian detector - only motions. And my CPU - desktop Intel i7 K-series. It's very fast.
And yes. The analysis of the FullHD videos will be slow. But you can:

1. scale down frames before detection and tracking;
2. use pedestrian detector not for all windows sizes - only for real pedestrians in specific video.

I think than real time for pedestrians detection - it can be done.

hello, trying to make the repository using ubuntu and getting a weird error.. i have to add that i have never tried this before and that i am not used to building from other people's repositories, could you possibly help me solve this?:

please help

[Atarashii]

thank you so much, that fixed the build issue, now that i have a .exe file, i have one last noob question that i would like to ask...

how do i now use the exe file? if double clicked it briefly opens a cmd window then closes instantly.

is it possible to apply this software to any video of my choosing? can it be applied to, say, a usb webcam?

edit: i managed to build and run .exe with input possible... load of issues along with command window and video file as shown below:

Any idea what the issue is and how I might address it? I am not an experienced Linux user so I appreciate any suggestions you have.

Hi!
You can try to use raw pointer on the CDetector (without unique_ptr).

@Atarashii Hello,I heard that you met one problem that I troubled:
CMakeFiles/MultitargetTracker.dir/build.make:62: recipe for target 'CMakeFiles/MultitargetTracker.dir/main.cpp.o' failed
make[2]: *** [CMakeFiles/MultitargetTracker.dir/main.cpp.o] Error 1

make[1]: *** [CMakeFiles/MultitargetTracker.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make: *** [all] Error 2

i have no idea where to start to fix this.please give me one hand that how you solve it? thank you very much!

@Nuzhny007 hello,Mr Smorodov,as i make Multitarget-tracker/build ,i meet the problem follow:

i have install opencv with opencv-contrib,while cmake,i set USE_OCV_BGFG, USE_OCV_KCF and USE_OCV_UKF,,then what should i do,please?thank you very much .

[HanWu1]

@RedOne88 hello, have you solved the problem?i also meet it ,can you me ?Thanks you!

[Nuzhny007]

Hi!
Try to set USE_OCV_BGFG=OFF in CMake before compilation (and USE_OCV_KCF and USE_OCV_UKF).
Function createBackgroundSubtractorCNT contains in opencv_contrib repository. I think than you dosn't compile it.

[HanWu1]

@Nuzhny007 Mr Smorodov, thanks for your reply. i have "make install" opencv3.2.0 with opencv-contrib3.2.0 succeed, as i cmake-gui ,i have set USE_OCV_BGFG=on (and USE_OCV_KCF and USE_OCV_UKF). configure and generate; then i Go to the build directory(Multitarget-tracker/build)and run make(make), then i meet this problem i just ask for you.

[HanWu1]

@Nuzhny007 Mr Smorodov,my workspace is ubuntu 16.04+ opencv3.2.0 (+opencv-contrib3.2.0),
(1)just now i cmake-gui,and configure (Multitarget-tracker/build) get the follow :

the above is what i do,can you help me ,thank you
(all the files i download from here i have no changed ,about the CMakeLists.txt)

[Nuzhny007]

The createBackgroundSubtractorCNT function is in opencv_contrib repository bgsegm module, here:
https://github.com/opencv/opencv_contrib/blob/master/modules/bgsegm/include/opencv2/bgsegm.hpp#L240
Check please this file in your copy of the opencv_contrib sources.

[HanWu1]

thanks very much. now i have changed bgsegm.hpp ,and begin to make the opencv3.2.0 and opencv-contrib3.2.0 agin.
