Welcome to the SFND_2D_Feature_Tracking wiki!

ToDo notes

18/03/2020:

  • Harris Corner Detector NMS implementation bug. The process allows for potential overlap between keypoints.
  • KNN implementation segmentation fault. Could not find the error. Update: Seems like it has to do with the cross_check parameter in the BF matcher type. When selecting cross check (true) then knn call fails. Otherwise it does run. However, the filter removes all matches???

19/03/2020:

  • The KNN issue seems to have disappeared. It does work when cross_check is false.
  • To be discussed with Roman the NMS bug in Harris.
  • AKAZE descriptor fails to run at the moment. Maybe needs AKAZE detector to start with.
  • SIFT requires non-free open_cv installation. (Re-built OpenCV with -DOPENCV_ENABLE_NONFREE=ON option).
  • Talk with Roman about:
  • the option to limit the number of keypoints to 50.
  • default parameters for detectors and descriptors
  • AKAZE
  • the distribution of their neighborhood size in keypoint detectors?

22/03/2020:

  • Project is finished and passed. No missing ToDo in the list. The NMS bug in Harris was discussed and seems like there is a bug indeed.
