Have you sovled the problem yet?

PlanNoa commented 4 years ago

I got same error in opencv 3.4.7 but I could solve this problem in 2.4.13 on windows 10.

filmnamu commented 4 years ago

The problem in ubuntu was not solved, but no error occurred in windows 10.

It seems that in opencv 3.1.0 ‘SparsePyrLKOpticalFlow’ is a member of cv::cuda, which means that I need to compile opencv with the cuda option activated. Does recompiling opencv with cuda, modifying the main.cpp by adding #include "cudaoptflow.hpp" and replacing cv::SparsePyrLKOpticalFlow by cv::cuda::SparsePyrLKOpticalFlow solves the problem (at least if you have a gpu) ?

Hi all, got the same problem, the last working commit for me is 1ecd253d4e2ef04fd11aee60338ed109eb1129bf "Added O - button to copy previous bboxes with object tracking"
