Eye detection and gaze estimation play an important role in many applications, e.g., the eye-controlled mouse in the assisting system for disabled or elderly persons, eye fixation and saccade in psychological analysis, or iris recognition in the security system. Traditional research usually achieves eye tracking by employing intrusive infrared-based(More)
This paper presents a lecture video structuring and analysis scheme to provide students an efficient way to access the lecture content. Instead of using color-based or histogram-based methodologies, we propose a new edge-based shot boundary detection algorithm to accurately rebuild the slide structure. The proposed approach can successfully resist the(More)

With the development of video coding and broadband network delivery, students can learn by lecture videos through the Internet without attending the class. However, watching lecture videos alone would be boring and make the self-paced learning difficult and inefficient, since students could not be monitored by the teacher and accompanied by classmates. In(More)
This paper presents a traceable fingerprinting scheme based on a multilevel user grouping strategy. In the proposed code structure, coding efforts for groups of users are apportioned to different levels of the code. Instead of making efforts to find one “highperformance” traceability code, we try to derive a generalized framework of fingerprints(More)
Since blackboards are the standard in the classrooms and are still used today, blackboard lecture videos are common in the lecture video recordings. However, it has been known that content-based blackboard lecture video analysis is challenging and thereby rarely be touched upon in the field of semantic computing. In this paper, we proposed a new structuring(More)
As the young generations grow up using applications like Facebook and as fans of social networking technologies, understanding the presentations of self in a virtual community becomes a worthwhile topic to be addressed. Drawing on the theory of dramaturgical theory (Goffman, 1959), this interpretive research was conducted to observe the self presentation of(More)
