Waleed Farag, Sanwar Ali · IMSA · 2006
In this paper, an introduction to Multimedia Information Retrieval (MIR) Systems is presented with justifications to their current widespread use. Explanations of the fundamental differences between MIR systems and standard text-based retrieval ones are also provided with highlights on the inadequacy of the use of keyword-based search techniques as the only modality in searching these archives. Several challenges facing MIR systems are expounded with the focus on bridging the semantic gap between human perception and the low-level features used by automated MIR systems to index multimedia data. The paper presents some of the promising future trends and discusses briefly areas that need further investigations.
