Code available: http://goo.gl/rkKXN The problem of multi-target tracking is comprised of two distinct, but tightly coupled challenges: (i) the naturally discrete problem of data association, \ie assigning image observations to the appropriate target; (ii) the naturally continuous problem of trajectory estimation, \ie recovering the trajectories of all targets. To go beyond simple greedy solutions for data association, recent approaches often perform multi-target tracking using discrete optimization. This has the disadvantage that trajectories need to be pre-computed or represented discretely, thus limiting accuracy. In this paper we instead formulate multi-target tracking as a discrete-continuous problem that handles each aspect in its natural domain and allows one to leverage powerf...

The video demonstrates a stable head tracking system that can run at 25fps on 1920x1080 video using a standard desktop computer. The system is capable of obtaining stable head images and is robust to temporary occlusions.

I wanted to implement kalman filters for each soccer player in the sequence. Along with this i used the hungarian algorithm to do data association. For this sequence i had truth data (on how many soccer players there were in each frame, as well as their locations). I used this truth data as the observation in the kalman filter. Since the observations were nearly perfect the tracker works very well. You can see that when a player leaves his tracking box is removed. When a player enters the scene a new tracking box is present.

Final Oral Examination of: Afshin Dehghan For the Degree of: Doctor of Philosophy (Computer Science) Firstly, a new framework for multi-target tracking that uses a novel data association technique employing the Generalized Maximum Clique Problem (GMCP) formulation is presented. The majority of current methods, such as bipartite matching, incorporate a limited temporal locality of the sequence into the data association problem. On the other hand, our approach incorporates both motion and appearance in a global manner. The proposed method incorporates the whole temporal span and solves the data association problem for one object at a time. GMCP is used to solve the optimization problem of our data association. GMCP leads us to a more accurate approach to multi-object tracking; however, it...
