Hi, I’m newbie about object tracking and I’ve been learning about this topic recently. I have a hobby project that will run on the Nvidia Jetson Nano development board. So this board has GPU and I want to use it (actualIy bought it for this). I’m currently using CSRT tracking algorithm for my project and actually I’m satisfied. But as a result of my research, this tracking algorithm does not support GPU which is in the opencv-contrib module. In fact, as far as I understand, it does not support any tracking algorithms in the opencv-contrib module. But why? Are tracking algorithms that cannot be parallelized? What is the story behind this situation? Thanks. ---

at least half the “tracking” module is basically obsolete and unmaintained. most of these trackers are behind the times. look into the `dnn` examples. there are trackers based on SiamRPN. ---
