why the trax waiting at hello message?

[wesley-stone]

I cmake kcf_vot and kcf_trax. but when I ran kcf_trax, it kept waiting at this line.
Is there any guide or suggestions?

You are running the tracker in TraX mode, this is the protocol used in the VOT toolkit. In this mode the tracker is supposed to wait for input from an external source (like an evaluation toolkit). Apparently there is no executable that would work in other mode, but it is reasonably easy to make one yourself, you just have to read images and pass them to the tracker.
