mytracker.update(detections); 目标框>=4个的时候，这一步耗时非常严重 #7

检测框大于4个的时候，update步骤耗时严重。 具体定位到_match(detections, res)步骤里的linear_assignment::getInstance()->matching_cascade()耗时非常严重。但小于4个目标框时感觉不到耗时。 博主，这是什么原因？

xiakj commented 4 years ago

我定位到大部分耗时都发生在linear_assignment.cpp中的这句： Eigen::Matrix<float, -1, 2, Eigen::RowMajor> indices = HungarianOper::Solve(cost_matrix);

Hey @xiakj, I came with the same problem, did you find your solution?
