I have tried different ways to implement the TrackerSamplerPF in OpenCV 3.3. But finally failed, and I can't find the sample from the official document. Thanks a lot.

I cannot find any sample. I don't know method but I found two bugs... looking for third...

Thanks for comment, I also find bugs when i implement TrackerSamplerPF, So does it means the method have something wrong in itself?

Do you use window or linux?

can you reproduce this on your configuration?

Actually, I was failed to reproduce this on my configuration for many times, and I followed the below method in this website:

http://answers.opencv.org/question/94...

and with the code in this website, i got the same ERROR:

OpenCV Error: Assertion failed (0 <= _rowRange.start && _rowRange.start <= _rowRange.end && _rowRange.end <= m.rows) in cv::Mat::Mat, file C:\OpenCV\source\modules\core\src\matrix.cpp, line 477

I don't know that is the method wrong or the internal bug in the TrackersamplerPF in opencv 3.3. Thanks

Have you try this code in your program? If you can reproduce results it would be helpfull to solve TrackerSamplePF bugs

yeap, I tried this code, and I got the same error, but I failed to fixed this bug after several efforts. Thanks

You cannot fixed this bug. You can avoid it change _std.rows in _std.cols here

and change this line in

int posMax[2];
minMaxIdx(_logweight, 0, &max_element,0,posMax);
Mat_<double> maxrow=_particles.row((int)posMax[1]);

But there is another bug and I don't know where...

Thanks, I can't find other bug either. So , maybe there are someone who have successfully implemented this methods. I hope I can find other substituted method.
