E-Chalk Lecture

SIOX was originally designed for object extraction in videos. The known background and known foreground is then learned from motion statistics instead of being provided by the user.
In the E-Chalk project, the board content is transmitted as vector graphics, producing thus a high quality image, while the video of the lecturer is sent as a separate stream. It is easy for the viewer to read the board but the lecturer appears in a separate window. To eliminate this problem, the lecturer is segmented from the video stream and his or her image is pasted onto the board image at video stream rates. The following videos provide an example of this process (MPEG 4 format):
