Wipe effect detection for video sequences

The design of automatic tools to allow content-based analysis, browsing, and retrieval is of paramount importance due to the wide spread of multimedia databases and to the enormous amount of information they contain. In this paper we present an algorithm tailored to the detection of editing effects such as wipes, which are widely used in television and movies production to emphasize scene changes. In our approach a computationally inexpensive although effective algorithm for wipe detection is presented. It is based on trajectory estimation of the boundary line between two successive frame belonging to the wipe region. The experimental results highlight the effectiveness of the proposed method.
