In this paper, we present the integration of a Wiki with lecture recordings using a tool called aofconvert, enabling the students to visually reference lecture recordings in the Wiki at a precise moment in time of the lecture. This tight integration between a Wiki and lecture materials allows the students to elaborate on the topics they learned in class as well as thoroughly discuss their own aspects of those topics. This technology can enable students to get actively involved in a collaborative learning process. One prerequisite for facilitating this consists in a reliable method for detecting slide transitions in lecture recordings. We describe an improved technique for slide transition detection in video-based/screen-grabbed lecture recordings when the object-based representation is not available. Our experiments demonstrate the accuracy of this new technique. A survey conducted with our students after using the Wiki in class completes this article and demonstrates which technical features are most important for such a Wiki.
