MediaTeam Oulu (MediaTeam), founded in 1997, is a research group of about 40 people at the Information Processing Laboratory in the Department of Electrical and Information Engineering at the University of Oulu. MediaTeam is a multidisciplinary research group, having researchers with backgrounds in electrical and information engineering, computer science and linguistics. MediaTeam conducts research on the features, use, and applications of multimedia and digital media types (image, sound, video, text) in information and communication systems. MediaTeam's main research topics are distributed computing, image and video processing, information hiding, language and audio technology, mobile services and packet networks. The research is carried out in a number of projects, the most important of which are briefly described below.
The Zirion - Mobile Media Containing Value Adding Services project funded by Tekes and industry concluded in 2008. The project focused on integrating digital watermarking technologies into new value-adding mobile services. The main results of the project included a demonstration whereby a web-address can be extracted from a picture taken with a mobile phone's camera from a poster containing watermarked image. A new audio protection technique was developed that utilizes audible watermarks as teaser-markers which can be transformed into inaudible unique fingerprints. A patent application on the audio protection method has been filed by an industrial partner.
The CAM4Home - Collaborative Aggregated Multimedia for Digital Home project funded by Tekes continued in 2008. The project is a part of the pan-European ITEA 2 program. The objective of the project is to create a metadata-enabled content delivery framework which allows end users and commercial content providers to create and deliver rich multimedia experiences for networked communities. The project has developed novel content-based metadata enrichment services for a common multimedia delivery platform. The results of the project have been published in journals such as IEEE Multimedia. A project demonstration won the bronze prize in the ITEA2 symposium.
The DECICOM - Decentralized Inter-Service Communications project funded by Tekes and industry continued in 2008. The project is among the leading Internet research projects in Finland, focusing on a new version of SIP, P2P-SIP. MediaTeam is coordinating the project, and the consortium includes many leading companies and universities spearheading the global standardization and development of the technologies in focus. Protocol development enables many novel applications beyond voice communication. Energy efficiency has Also been studied in empirical and simulation environments.
The ExpeShare - Experience sharing in Mobile Peer Communities project funded by Tekes continued in 2008. The project is part of the pan-European ITEA 2 program. The international project consortium comprises of 25 industrial and academic partners from Finland, France and Spain. The project focuses on developing a service environment that supports converged multimedia services, and experience sharing in communities over peer-to-peer networks. A community-centric service architecture that leverages the collaboration of peer-to-peer technologies and web services has been implemented, along with innovative pilot services.
The UBI - UrBan Interactions program expanded in 2008, as the new UbiCity and UbiGo projects received funding from the ERDF and the City of Oulu. The UbiLife project funded by Tekes, the City of Oulu and industry started already in 2007. The objective of the UBI program is to introduce a visible change into society by building a functional prototype of a future ubiquitous city in Oulu. This involves long-term basic research on ubiquitous computing, and an investment in new types of computing infrastructure. The UbiCity project will deploy, in three phases in 2009-2011, a cluster of large interactive public displays and a heterogeneous sensor network in downtown Oulu. The infrastructure facilitates developing novel types of prototype applications and services, which are evaluated as short-term small-scale demos, and as long-term large-scale field trials in the true environment of use with genuine end users. The UbiGo project of the Oulu University of Applied Sciences with their expertise stimulates and coordinates SME participation in the UBI program. The multidisciplinary UBI consortium includes research groups from the University of Oulu, the Helsinki Institute for Information Technology, the Helsinki University of Technology, the University of Art and Design Helsinki, the University of Lapland, the Oulu University of Applied Sciences, and VTT Technical Research Centre of Finland. By the end of 2008, the UBI program had produced 35 international scientific publications and 7 theses.
The Digital Watermarking of Speech and Holograms project funded by the Academy of Finland continued in 2008. The project focuses on digital rights management technologies, especially digital watermarking of speech signals and holographic data. A method for binary image watermarking was tested and a watermarked hologram was designed and implemented.
Junzhao Sun, an Academy Research Fellow, continued his research on cross-layer optimization for wireless sensor networks. The general objective is to bridge the gap between the technologies needed for modeling, processing and networking by investigating high-level cross-layer optimization techniques in a top-down fashion. Special attention has been paid to query processing and data gathering in sensor networks.
Juhani Toivanen, another Academy Research Fellow, continued his research on the features of emotional prosody in spoken Finnish, aiming at a general model taking into account both linguistic (phonological) and signal (phonetic) aspects of prosody. He has also been working towards a descriptive framework capable of displaying the so-called non-modal features of intonation (phonation) in emotional Finnish speech.
