Comparative Study of Marker-based Detection and Tracking of PC in the Video Sequence Acquired by the Mobile Camera for Visual Call Center Applications

摘要

The call centers in which video communication is available, visual call centers, are supposed to be an efficient way of PC troubleshooting. Users take the video of their computer with handy cameras and send the video to the operators. The operators can confirm the matter directly so that they can give more reasonable advice to users. However, viewing the video directly has the threat of privacy violation. To overcome this problem, a method that can detect computer from the video and eliminate other objects is needed. In this paper, a marker-based PC detection method is proposed and several typical tracking methods are compared in order to fine out the appropriate ones. The accuracy and robustness of both the marker-based methods and the tracking methods are shown by experimental results.
