Abstract
Online video lectures are becoming commonplace in higher education. One problem is that the instructor might block what he has written on the board. In our project, we reconstruct the online lecture video so that the information on the whiteboard is always available to the viewers. The background subtraction, object tracking, and object replacement technique have been used to reconstruct the video. The complete access of the whiteboard information is obtained by replacing the lecturer/object with whiteboard information from the future frames or the past. The object is detected by using background subtraction method and is tracked by object tracking technique. The algorithm can be implemented for different board conditions and video resolutions.
