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...
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.
Very simple example of Multi object tracking using the Kalman filter and then Hungarian algorithm. Visit website for code http://studentdavestutorials.weebly.com/ if you would like get those lil bugs, http://www.hexbug.com/nano/

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.

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...
Another draw cut on energy shot bottle. Set the carton and milk jug up to practice on fluidity of cutting multiple targets. Lemme know what ya thunk
This simulation describe a estimation project on multiple target tracking. The simulation is in Gazebo and the control done in ros. Each target is assigned ab Kalman filter. The algorithm works only on constant number of targets.

Part 1: https://youtu.be/PP7wXdcLZHo Blob detection algorithm using Kalman Filter objects to predict blob positions and track across successive. The algorithm is capable of tracking through long-term occlusion with some success. It has been designed for the tracking of small, fast-moving objects such as bats. This is an improved version of the algorithm used in Part 1 with several changes made to the tracking logic. Results are shown for a number of different motion paths, object types and lighting conditions. Using OpenCV 3.1 and MS Visual Studio 2015.
