Joint Probabilistic Data Association Tracking (JPDAFTracker)

JPDAFTracker is a tracker based on joint probabilistic data association filtering.

Requirements

• OpenCV
• Eigen

How to build

JPDAFTracker works under Linux environments. I recommend a so-called out of source build which can be achieved by the following command sequence:

• mkdir build
• cd build
• cmake ../
• make -j<number-of-cores+1>
