Install opencv_contrib Tracking package

edit

Hey there I simply want to use the tracking package of the opencv3 contrib package in my ros kinetic.

I figured already out that in particular the tracking package is not contained in one of the following:

[STATUS]OpenCV_LIBRARIES [STATUS]opencv_calib3dopencv_coreopencv_features2dopencv_flannopencv_highguiopencv_imgcodecsopencv_imgprocopencv_mlopencv_objdetectopencv_photoopencv_shapeopencv_stitchingopencv_superresopencv_videoopencv_videoioopencv_videostabopencv_vizopencv_arucoopencv_bgsegmopencv_bioinspiredopencv_ccalibopencv_cvvopencv_datasetsopencv_dpmopencv_faceopencv_fuzzyopencv_hdfopencv_line_descriptoropencv_optflowopencv_phase_unwrappingopencv_plotopencv_regopencv_rgbdopencv_saliencyopencv_stereoopencv_structured_lightopencv_surface_matchingopencv_textopencv_xfeatures2dopencv_ximgprocopencv_xobjdetectopencv_xphoto [STATUS]OpenCV_LIB_COMPONENTS [STATUS]opencv_calib3dopencv_coreopencv_features2dopencv_flannopencv_highguiopencv_imgcodecsopencv_imgprocopencv_mlopencv_objdetectopencv_photoopencv_shapeopencv_stitchingopencv_superresopencv_videoopencv_videoioopencv_videostabopencv_vizopencv_arucoopencv_bgsegmopencv_bioinspiredopencv_ccalibopencv_cvvopencv_datasetsopencv_dpmopencv_faceopencv_fuzzyopencv_hdfopencv_line_descriptoropencv_optflowopencv_phase_unwrappingopencv_plotopencv_regopencv_rgbdopencv_saliencyopencv_stereoopencv_structured_lightopencv_surface_matchingopencv_textopencv_xfeatures2dopencv_ximgprocopencv_xobjdetectopencv_xphoto [STATUS]OpenCV_INCLUDE_DIRS [STATUS]/opt/ros/kinetic/include/opencv-3.2.0-dev/opt/ros/kinetic/include/opencv-3.2.0-dev/opencv

So I guess I have to install the tracking package myself but how do I do that?

I have installed sudo apt-get install ros-kinetic-opencv*

Well actually my main problem is: That I have the following code (tracker.cpp):

#include <opencv2/opencv.hpp>
// selectROI is part of tracking API
#include <opencv2/tracking.hpp>

using namespace std;
using namespace cv;


int main (int argc, char **arv)
{
    // Read image
    Mat im = imread("image.jpg");

    // Select ROI
    Rect2d r = selectROI(im);

    // Crop image
    Mat imCrop = im(r);

    // Display Cropped Image
    imshow("Image", imCrop);
    waitKey(0);

    return 0;
}

And when I run:

g++ -M tracker.cpp

I even get:

....
 /usr/local/include/opencv2/tracking.hpp \
 /usr/local/include/opencv2/tracking/tracker.hpp \
 /usr/local/include/opencv2/tracking/feature.hpp \
 /usr/local/include/opencv2/tracking/onlineMIL.hpp \
 /usr/local/include/opencv2/tracking/onlineBoosting.hpp \
 /usr/local/include/opencv2/tracking/tldDataset.hpp

Building my package leads to the following error:

error: ‘selectROI’ was not declared in this scope
     Rect2d r = selectROI(im);
