NOTE:as in practical realtime MOT, the detector doesn't run on every single frame. Args: dets (Numpy array): detections in the format [[x0,y0,x1,y1,score], [x0,y0,x1,y1,score], ...] Returns: a similar array, where the last column is the object ID. rérérNz New tracker: Ú.éÿÿÿÿzRemove tracker: )rr)r ÚnpÚzerosÚlenr Ú enumerateZpredictÚanyÚisnanÚappendÚmaZ compress_rowsZmasked_invalidÚreversedÚpoprÚwhereÚupdateZface_attributesrÚprintÚidZ get_stateZtime_since_updateZ hit_streakr Z concatenateZreshaperZ predict_numÚempty)r ZdetsZimg_sizeZadditional_attrZdetect_intervalZtrksZto_delÚretÚtZtrkÚposÚmatchedZunmatched_detsZunmatched_trksÚdÚirrrr s` &   ÿ &   ($ ÿ ÿÿÿ z SORT.updateN)rrr)Ú__name__Ú __module__Ú __qualname__Ú__doc__rr rrrrrs r)ÚnumpyrZ"facexlib.tracking.data_associationrZ facexlib.tracking.kalman_trackerrÚobjectrrrrrÚs
