Bodo Rosenhahn

Bodo Rosenhahn studied Computer Science (minor subject Medicine) at the University of Kiel. He received the Dipl.-Inf. and Dr.-Ing. degrees from the University of Kiel [1] in 1999 and 2003, respectively. From 10/2003 till 10/2005, he worked as post doc at the University of Auckland [2] (New Zealand), funded with a scholarship from the German Research Foundation (DFG [3]). In 11/2005-08/2008 he worked as senior researcher at the Max-Planck Insitute for Informatics [4] in Saarbruecken. Since 09/2008 he is Full Professor at the Leibniz University Hannover [5], heading a group on automated image interpretation [6]. His research interests are in the area of digital signal processing and machine learning with applications in computer vision, multi sensor fusion and optimization. His works received several awards, he published more than 180 research papers, journal articles and book chapters, holds more than 10 patents and edited several books.

Multi Object Tracking for cells, microorganisms and human motion analysis

In this talk I will summarise recent results on multi object tracking using the tracking-by-detection paradigm. The challenge is to use detections (e.g. bounding boxes of objects in images) as input and the goal is to generate consistent trajectories over the entire sequence. This task can be cast as a network flow graph, which can be globally optimised using a linear programming (LP) formulation. I will present selected basics about (integer) linear programming, some simple discrete optimization tasks (e.g. graph matching), their respective LP formulations and finally explain graph based tracking and its optimisation. The talk continues with some applications, recent results e.g. on the MOTA benchmark and concludes with future research strands.
