Abstract

E-learning is an emerging new education approach that augments learning experiences by integrating multimedia and network technologies. As an integrated part of e-learning, the lecture videos captured in classrooms contain most of the instructional content. Effective use of these videos, however, remains a challenging task. This paper reviews previous research work on capturing, analyzing, indexing, and retrieval of lecture (instructional) videos, and introduces on-going research efforts related with instructional videos. This paper compares instructional video to other video genres and addresses its special issues anddifficulties. We present the current challenges in content-based indexing and retrieval of instructional videos. Improving these techniques for lecture videos has significant educational and social benefits.
