Efficient Summarizing of Multimedia Archives Using Cluster Labeling

In this demo we present a novel approach for labeling clusters in minimally annotated data archives. We propose to build on clustering by aggregating the automatically tagged semantics. We propose and compare four techniques for labeling the clusters and evaluate the performance compared to human labeled ground-truth. We define the error measures to quantify the results, and present examples of the cluster labeling results obtained on the BBC stock shots and broadcast news videos from the TRECVID-2005 video data set.
