Object tracking is the task of taking an initial set of object detections, creating a unique ID for each of the initial detections, and then tracking each of the objects as they move around frames in a video, maintaining the ID assignment. Tiling effectively zooms your detector in on small objects, but allows you to keep the small input resolution you need in order to be able to run fast inference. /ExtGState 44 0 R [ (\135\054) -241.02 (Y) 29.9974 (OLO\133) ] TJ 0 g [ (tr) 14.9914 (ating) -250.988 (the) -251.009 (low) -250.011 (accur) 14.9852 (acy) -250.981 (of) -251.005 (state\055of\055the\055art) -251.007 (object) -251.002 (detector) 10.0155 (s) ] TJ /R11 11.9552 Tf [ (or) -293.007 (recognition\056) -438.008 (Ev) 14.9877 (en) -293.01 (though) -291.995 (DORI) -292.995 (criteria) -293.01 (is) -292.015 (met) ] TJ 82.684 15.016 l >> Annotating images and serializing the dataset Q /R9 14.3462 Tf Unfortunately, I could not find a clear answer to my question.
