Opencv tracking example


Median flow tracker code coming soon


  • Simple median flow tracker base od goodFeaturesToTrack
  •  calcOpticalFlowPyrLK
  • TODO complete forward backwards tracking and feature filtering. I already have forward, backwards LK tracker, without filtering (just prepared NORM computation).
  • TODO complete redetection. White rectangles are redetection with online learning by RTrees opencv 3.1 support. Rtrees work great. I only need better features. Do you have any advice or tips?
  • From the initial Rectangle is generated several positive examples and negatives from the rest of image. Rtrees learning and prediction can run very fast. I still haven't got a good features. Feature extracting took some time to. 
  • TODO Forward backward + redetection. 
  • 300 lines of code 
Final result will be 

TLD tracker

I would like to release this in 4 next tutorials. 

Forward backwards median flow tracker

Rtrees learning ( new features ) and prediction with single scale detection sliding window

  1. hey vystavil, is your code coming out soon? I'd be interested in maybe using it for my own project.
