accelerating the GOTURN (opencv tracker) but the results are not stable

I am doing the job accelerating the GOTURN (opencv tracker) network with GPU on tx1 now. The program can run normally on tx1 (Ubuntu 16.04, L4T R28.2, tensorRT 3.0.4), but the results of the tracking are not stable with FP16 or FP32. I tried a lot of methods and the GOTURN didn’t work as stable as running with opencv. So could anybody tell me what might be caused or could you share how you did this job?
Thanks a lot.

Hi @Bruce-Lee-LY were you able to get an accelerated GOTURN to work ?
