IRIS - Image retrieval for images and videos

. The large amount of available multimedia information (e.g. videos, audio, images) requires efficient and effective annotation and retrieval methods. The System IRIS (Image Retrieval for Information Systems), which was developed at the University of Bremen in the AI group, is designed for content-based retrieval of single images. As videos become a more important role in the frame of multimedia, we want to make videos available for IRIS.The first step is the detection and extraction of shots from a video using a histogram based method. The second step is to combine the images in a shot to a single image. This image describes the shot (Mosaicing-technique) and can be analyzed with IRIS. 1 The IRIS-System In order to retrieve images it is more sophisticated and usual for human beings to use natural language concepts, e.g. mountainlake, than syntactical features, e.g. red region left up. This leads to a content-based image retrieval. Furthermore, it is unreasonable for any human being ..
