jakaskerl Thank you very much for your kind reply.
1- "the whole TrackableObject class runs on host" and "tracking and their links all run on the device". Do you mean that the creation of the objectTracker is done on the device and the process of tracking and execution is done on the host computer ?
2- I implemented my own tracking function. The execution time is different from host mode to standalone mode. Is this explained by the fact that in host mode it runs on the computer but in standalone it runs on the RVC2 ?
Thank you for your support
