题目：SIMPLE ONLINE AND REALTIME TRACKING WITH A DEEP ASSOCIATION METRIC
作者: Nicolai Wojke †, Alex Bewley? Dietrich Paul †
1. sort based on the depth information is added: REID, IDswith 45% reduction;
2. Direct detection with neglect of the class distinction;
3.kalman: X=[Xcenter, Ycenter, ratio, Hight, Xcenter* , Ycenter*, ratio* ,Hight*]
4. The appearance characteristics stored and then compared,
The time allowed is 30;
6.C(i,j)=@*d1(i,j)+(1-@)*d2(i,j)
d1: kalman amount and predicted observables
The apparent features cosine distance: d2
7. Code: matching said cascade: REID → IOU, which contains the location of the threshold limit
8 is a front three experimental
problem found:
1. The association is not accurate, identity transformation occurs, but this is after reduced;
2.FP higher, as explained herein observation time is too long resulting 30;
3. Replace REID effect how bad it
Thinking:
1. only use location information, did not really use the speed information;
2. The optical flow information
