Tracker and age limite

TompoussTompousss

Hello,

I want to use the ObjectTracker but I don't see how to define the age limite of each tracked object. I can see the attributes there in the Tracklet, but how to set a limit, so we don't keep track of object for ever and don't get flying empty boxes for 3 sec ?
Also, has anyone try to go higher than 65 FPS ? In my case using SHORT_TERM_KCF leads to 3 FPS, and SHORT_TERM_IMAGELESS, ZERO_TERM_COLOR_HISTOGRAM and ZERO_TERM_IMAGELESS all give around 63 FPS. So I am not sure to get the difference between short term and zero term image less actually. Both seem to be limited to the speed of my detection anyway (which is around 65 FPS) and don't increase the speed, they just add ids.
I am trying this using Object tracker on video.

Thanks

Hi @TompoussTompousss
It's not possible to limit tracklet age through the API atm. You can manually implement the logic by counting the frames in which the tracklet is LOST and automatically remove them after a certain number.

Thoughts?

Hi @jakaskerl ,

Sorry for the delay.
I see, I will do it manually then.

Another question related to pipeline node and trackers, but using the camera online this time:

I would like to use a nn to detect an object on an image, and then only rely on a tracker to continue following that object. Some tracker are really fast, and with MOSSE I can follow the object up to 100 fps when the tracker is running alone (I tried to instantiate a MOSSE tracker with a script and that was the speed). My problem is that my nn node is still processing and slowing down the fps. Is there anyway to delete or disable a node from a pipeline on the fly since I don't need it once the tracker has been initialized ?

And is there also an easy way to run a nn without using the pipeline and a nn node ? Like in the script ?

Thanks for your help.

Hi @TompoussTompousss
Try this. It should speed up the pipeline after turning off NN.

Thanks,

Hi @jakaskerl ,

Thanks a lot, that's perfect ! And with that method I could solve also my problem about switching from one nn to another and also sending data from the script to the new nn.
