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.

Our interacting multiple pedestrian tracking method incorporates a prior knowledge about the behaviour of the targets. The motion is modeled by considering 4 cases of pedestrian behaviours: going straight; finding the way; walking around and holding position. The first three cases indicate that a pedestrian is moving and they are modeled by constant velocity models and the last one is a constant position model. Those models are combined through the interactive multiple model particle filter algorithm. High level behaviours, collision avoids and flocking, are included to model a more realistic pedestrian motion.
Template for the famous MOT paradigm (Pylyshyn&Storm, 1998 Scholl&Pylyshyn, 1999) is added to the EventIDE template gallery. The template contains a code generating unpredictable trajectories for occlusion-free motion of multiple objects. Trajectory generation is a random process controlled by several initial parameters that can be customized. In addition, the template demonstrates how to use recurrent events to create a time-precise animation with EventIDE. This video shows a single MOT trial with 10 moving objects and 4 tracking targets.
Efficient Spatio-Temporal Data Association Using Multidimensional Assignment for Multi-Camera Multi-Target Tracking (BMVC 2015) This paper proposes a novel multi-target tracking method which jointly solves a data association problem using images from multiple cameras. In this work, the spatiotemporal data association problem is formulated as a multidimensional assignment problem (MDA). To achieve a fast, efficient, and easily implementable approximation algorithm, we solve the MDA problem approximately by solving a sequence of bipartite matching problems using random splitting and merging operations. In this formulation, we design a new cost function, considering the accuracy in 3D reconstruction, motion smoothness, visibility from cameras, starting/ending at entrance and exit zone, and f...

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.
