Let A and B represent the tracking gate and the ground-truth bounding box respectively.
Assumed that the sets of the valid measurements and the cumulative measurement are, respectively, expressed by: tilde{Z} k)={left{{boldsymbol{z}}_{i,k}right}}_{i=1}^{m_k} (15) {tilde{Z}}^k={left{tilde{Z}(j right}}_{j=1}^k (16)where z i,k is the ith valid measurement, and m k is the number of all valid measurements in the tracking gate at time k.
The research result shows that the orientation detection system using L-shape reticle has a good effect on space-filtering, the signals that the orientation detection system sends out are easy to be processed by computer, its self-adapting tracking gate has a strong anti-interference ability, and the whole system's searching and tracking performances are quite high.
The dimension of the patterns on the reticle of the system in practical applications is designed and an analysis of the principle of abstracting the orientation information of the target and the effects and formation method of self-adapting tracking gate is presented.
Pass through, continue along track, ignoring gate in corner.
Officials said that as the truck tried to cross the tracks, the gates had started coming down but were not yet horizontal.
Follow signpost to Malmsmead to the left (muddy area), then cross bridge over river, go up track, through gate and then to road.
In order to provide space for the railroad tracks, the gates of Fort Jackson had to be removed.
I tracked down Gates by phone at J.F.K. on Friday after he had talked to the president and agreed to go to the White House for a symbolic beer with the man he labeled "a rogue policeman".
Near-membrane fluorescence signals track the gating of N-type Ca2+ channels with a kinetic resolution of about 10 ms, provide a simultaneous and independent readout from several channels, and allow their locations to be mapped with sub-micrometer spatial resolution.
