The Lowlands team at TRECVID 2007

In this report we summarize our methods and results for the search tasks in TRECVID 2007. We employ two different kinds of search: purely ASR based and purely concept based search. However, there is not significant difference of the performance of the two systems. Using neighboring shots for the combination of two concepts seems to be beneficial. General preprocessing of queries increased the performance and choosing detector sources helped. However, for all automatic search components we need to perform further investigations.
