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)
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.

This paper presents a feasible system for multimedia fingerprinting. One of the important problems of fingerprinting is watermarking strategies for the fingerprints, in other words, where to embed and how to embed. We address these two major problems of fingerprint-watermarking for multimedia in the proposed content-adaptive watermarking scheme. First, the(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)
We analyzed the occurrence and mechanisms of fusidic acid resistance present in staphylococci isolated from 59 healthy volunteers. The fingers of the volunteers were screened for the presence of staphylococci, and the collected isolates were tested for resistance to fusidic acid. A total of 34 fusidic acid resistant staphylococcal strains (all were(More)
