previous problem • The lengths of ground truth tracklets are equal. tracklet tracklet tracklet tracklet Low Z value tracklet
solution • Cut trajectory to tracklet randomly tracklet tracklet tracklet tracklet
Previous problem • The scales of some thresholds are wide. Feature 1 Feature 5
solution • Quantize these features’ threshold with respective bins. • Quantize the difference of min and max value with difference bin.
To do • Human detection • Build ground truth • association
The end • Thank you!
