Title of thesis ：PolyTrack: Tracking with Bounding Polygons

Original author ：Gaspar Faure

Summary

In this paper , We propose a new method called PolyTrack Fast multi-target tracking and segmentation using boundary polygons .Polytrack The object is detected by generating the heat map of the key points in the center of the object . For each of them , Rough segmentation is achieved by calculating the boundary polygon on each instance instead of the traditional boundary box . Tracking is by taking two consecutive frames as input , A center offset is calculated for each target detected in the first frame to predict its position in the second frame . In order to reduce the ID Number of switches , Kalman filter is also used . Because our target application is auto drive system , We apply our method to urban environment video . We are MOTS and KITTIMOTS Training and evaluation on data sets PolyTrack. It turns out that , Tracking polygons can be a good substitute for bounding box and mask tracking .
