Module DescriptionAudio and video files are becoming more important in our daily work as well as our leisure lives. In contrast to earlier times, today’s storage capacities and transmission bandwidths can easily cope with large amounts of data. But still, effective search and efficient retrieval of this audio-visual data is not supported properly, and still mainly relies on external meta-data in most state-of-the-art systems. In this module, selected aspects of multimedia database systems are investigated and insights on the used techniques are given. In particular, the module deals with content-based retrieval of multimedia data. The fundamental question is the efficient storage and the later retrieval of multimedia documents. Commonly used retrieval models, as well as an comparison of different auio-visual database techniques are discussed. Typical features of current (commercial) database systems for multimedia information processing are also presented.
Module OutcomesOn completion of this module, the students have been made aware of the challenges and problems which arise from multi-media retrieval and multi-media storage. This covers technical aspects (algorithms, implementations, etc.) and also psychological aspects (e.g. psycho-acoustics, perceived similarity, lossy compressions, etc.). Furthermore, the students will be able to discuss the strengths and weaknesses of different approaches to multi-media retrieval and will be able to competently propose solution strategies to presented problem scenarios. Furthermore, due to the topic’s actuality and the steady progress of the scientific community, students will have to deal with scientific source material, increasing their awareness for proper scientific workflows.
