Hi all,

I understand that using a different value for psr_threshold in CSRT tracker affects the reliability of the tracker. We made some tests and found out, that the default value of 0.035 is too small for us. Is there any recommended way of changing this parameter instead of just wild guessing based on empirical testing? Can somebody please explain the meaning of this parameter? What is a reasonable minimum or maximum value for psr_threshold ?

KCF tracker, for example, has the params::detect_thresh value which seems to be a percent reliability value so it's easy to use.

Thanks.

Thanks for all the valueable info. A.

Hi all,

looking at the tracking API I was wondering if the init or update methods can be fed with GpuMat data instead of Mat. I.e. if I have decoded data in GPU memory, can I use the tracking API directly or should I copy data from GPU to host first?

Thanks.

Thanks, that's what I was thinking. There are some interesting projects like this one which show that the tracking algos

I see, thanks. But to come back to the original question, because I am still not clear about it. Does that mean that we

Hm, that's a bit surprising though, because OpenCV used to inform about and already has CUDA support ( https://docs.open

Ok, does that mean that Yolov3 (which has been added to OpenCV) cannot use cuDNN for maximum speed? If not, are there pl
