Tracking by Detection

This software package provides a reference implementation for the classic object tracker used in:
The tracker operates in three stages: First, objects are detected in each frame independently using the DPM object detector by Ross Girshick and Pedro Felzenszwalb. Second, all detections with a positive score are associated to detections in the next frame using appearance and the bounding box overlap. Prediction is performed using a Kalman filter and we associate detections between both frames via the Hungarian method for bipartite matching. To gap occlusions and missed detections, we also associate tracklets with each other in a third stage. Similarly to the second stage, the Hungarian algorithm is employed but this time based on an occlusion sensitive appearance model and regression of the bounding boxes in one tracklet from the bounding boxes in the other tracklet. The algorithm outputs all associated tracklets which are longer than three frames.
