How much speed up is expected if we use parallel programming like cuda?

Hi, I'm curious about what happen if we take another step for this awesome algorithm and add GPU support to it? does the performance may be added dramatically ?

Hi, if you want a faster version of this algorithm you can check OpenCV contrib tracking module, where you can find c++ implementation of this tracker (CSRT tracker). It runs approximately at 30 FPS, while multi-thread version (which runs still on the CPU only) runs at 50 FPS. I think that GPU implementation could speed up calculations like Fourier transform and other per-element operations, but I cannot estimate how much.

Thanks @alanlukezic

Hi, Alan! I am an university student working in a project where I need to track a ball in real time. Of all the trackers I tried, CSRT Tracker is the best one by now, but I just get 15fps.

I am running the CSRT Tracker of OpenCV with C++ in a video stream of 512x424 pixels. Without the tracker I get 28fps, but when I enable the tracker I get just 15fps. I tried it in a Macbook Pro 2019 and also in a HP Elitebook, and I get similar results.

Under which circumstances should I be able to track at 30fps?

Thanks a lot! Jordi
