Completed Projects

Geotagged Videos

Geotagging, the process of combining geographical information with media files, is quite common with images nowadays. For videos, however, this trend has not become popular yet. This project presents both techniques for recording those geotagged videos and for displaying them on an interactive map. [more]

Interactive Hyperlinked Videos in Social Networks

The goal of this project is to develop novel interfaces to allow users to interact with hyperlinked videos. A second research question focuses on technical challenges like tracking of hyper objects and simultaneous multi-user interactions.


Media Retargeting

Media retargeting is about the automatic adaptation of images and videos for smartphones and other small handheld multimedia devices."

High Dynamic Range Video

High Dynamic Range (HDR) imaging is a technique to overcome the limitations of traditional Low Dynamic Range (LDR) imaging equipment. While LDR capturing devices often cannot capture a scene's full range of brightness variations, leaving under- or overexposed areas in the image, HDR imaging provides algorithms to produce pictures that preserve detail in the dark and bright regions simultaneously. This set of methods can be extended to create HDR videos in real-time.

MoCA - Movie Content Analysis

Automatic content analysis of audio and video data analysis provides semantic information for indexing and retrieval.

While digital fast-paced action games are played by a broad audience among the whole world, their educational value is uncertain to say the least. The project Word Domination is a step towards combining these highly motivating games with learning content to create an enjoyable serious game. [more]

Distance learners in traditional online exercise and tutoring systems often get stuck with questions for which they need the help of a tutor or colleague. Learning alone can also be frustrating. In our Communication And Tutoring System CATS we have integrated the possibility to dial up a tutor and/or to setup immediate group communication with other distance learners using Internet videoconferencing technology.

Within this project, two eqution-based congestion control protocols were developed. Their aim is to provide congestion control for multicast (TFMCC) and for non-adaptable flows, two areas where TCP congestion control does not work.

In the framework of COST (Cooperation in Scientific and Technical Research) this European project focusses on algorithms and protocols for multicast communication in the Internet.

Our approach for secure multimedia applications is to implement and improve the latest results in highspeed cryptography research and to develop new scalelable security and payment protocols.

The Interactive Home-Learning Project aims at the learning student at home who usually only has a low bandwidth access to the Internet.

In papercrafting, virtual 3D models are unfolded to 2D cutout sheets. Once cut out with scissors and glued together, they resemble the virtual object as paper model. But unfolding is not always trivial or even possible, because self-intersections in the flattened model can emerge which make the assembly infeasible. This software allows to transform 3D models stored as DXF file into a cutout sheet. In contrast to commercial solutions, the application allows to try different optimization strategies which can yield better results in case of complicated objects.


We are still in the process of finding unfolding strategies which perform equally well for all kinds of models. You may use our open source project as a basis to tackle the problem yourself.

E-NEXT is an FP6 Network of Excellence that focuses on Internet protocols and services.
The general objective of E-NEXT is to reinforce European scientific and technological excellence in the networking area through a progressive and lasting integration of research capacities existing in the European Research Area (ERA).
For more information on our E-NEXT activities, check our MANET-pages.

In the ECHO-Project (European Chronicles Online) a software infrastructure is developed to support digital film archives and to provide Web-based access to collections of historical documentary films of great international value.

Development of a multimedia library which provides effective mechanisms for storage and retrieval of different media types.

The aim of FleetNet is to develop technologies for communication between vehicles that will be connected and integreted into the internet via an ad-hoc communication system.

The Interactive Home-Learning Project aims at the learning student at home who usually only has a low bandwidth access to the Internet.

The Interactive Media on Demand (IMoD) system is the first generic recorder for interactive media streams (i.e. data streams produced by applications like shared whiteboards, distributed virtual worlds etc.).

The L3 project aims at establishing several multi-media learning centers which are spread all over germany. Learners can meet in virtual classrooms even though they may be located in distant cities.

A location library


The Mobile Business Research Group is going to build up technology and a generic software platform for location-based and context-based applications.

The project "Mobile Ad-Hoc Networks" is a long-term internal research project grouping together all activities of "PI4" that are related to this topic. Sub-topics of this project are e.g. "Vehicular Ad-Hoc Networks", and "Sensor Networks".

The mlb is a sophisticated electronic whiteboard, a tool for presenting and editing documents. Its application field includes both shared and local conferencing environments.


The project Mobile Learner aims to improve the interaction between learners in distributed teaching and learning scenarios.

Planet PI4 is a P2P shooter game, developed by the University of Mannheim and the TU-Darmstadt. It is a fully implemented third-person 3D space shooter for multiple players connected by a peer-to-peer overlay network.

The DFG research group QuaP2P focuses on the development of a benchmark methodology for P2P systems. The main application scenarios are P2P-Search Overlays, P2P-Document and System-Management, P2P-Management Mechanisms and P2P-Realtime Games.

Achievement systems originate from online entertainment systems like Microsoft’s XBox Live or Blizzard’s World of Warcraft. The original intention is to keep track of a user’s deeds in the virtual gaming world and to reward her with records in her profile. The "Reward System" transfers this achievement concept into the real word.

RTP/I is an application-layer protocol for the transmission of interactive media with real-time characteristics, involving user interaction. RTP/I captures the common aspects of the interactive media class, enabling the development of generic services (e.g. late-join, recording) for interactive media.

Spontaneous Virtual Networks - methods for the controllability of heterogeneous communication networks. In the first funding period of the project our subproject was focussed on two test applications for SpoVNet, namely Online Games and Video Streaming, developing exemplary applications for practical testing of the realtime behaviour of SpoVNet.
