Abstract
An essential goal of structuring lecture videos captured in live presentation is to provide a synchronized view of video clips and electronic slides. This paper presents an automatic approach to match video clips and slides based on the analysis of text embedded in lecture videos. We describe a method to reconstruct high-resolution video texts from multiple keyframes for robust OCR recognition. A two-stage matching algorithm based on the title and content similarity measures between video clips and slides is also proposed. © 2003 ACM.
