In today’s Grand Challenge session at ACM Multimedia 2013, two paper-solutions for the MediaMixer / VideoLectures.NET challenge on temporal segmentation of e-learning videos were presented:
1) MUST VIS system (IDIAP Switzerland) offers an appealing visualisation of video-to-video and segment-to-segment linking based on video analysis and tagging, and their associations. A first demo was presented which can be seen at http://portal.klewel.com/graph
2) The Hasso Platner Institute (HPI) presented a solution based purely on OCR analysis of the accompanying lecture slides, using common partners to provide for solutions for Global and Partial Segmentation of the video, being more accurate than the use of shot segmentation techniques relying on transitions between video frames. The slideset is available at http://www.yanghaojin.com/research/ACM-MM-GC-DEMO/
While the global Grand Challenge winners will be announced tonight, the MediaMixer project has already selected their Grand Challenge winner, and congratulates IDIAP Switzerland on an appealing visualisation of video fragment associations which can be of great usability value in our VideoLecturesMashup demonstrator. The authors win a chance to visit the VideoLectures team in Ljubljana, Slovenia and collaborate with us on a new version of VideoLecturesMashup!
