Removing occlusion using even odd interlacing for efficient class room teaching

Abstract

Occlusion is any unwanted object that hinders the view of the objects or scenes behind them. Many times the viewer cannot comprehend what is present in the background due to the continuous presence of the occlusion. In a similar setting of classroom /boardroom occlusion of the blackboard/whiteboard contents because of the presence of certain objects like teachers and other students walking in front of the board, leads to missing out on the valuable components of board contents. Capturing the board content in presence of the such occlusions is a difficult task. The work presented in this paper focuses particularly on the meeting and/or classroom that use whiteboard/blackboard heavily for lectures, project planning meetings etc. In these scenarios, boards are considered to be necessary. But the contents of the boards are lost most of the time without even being archived. Consequently, a tool to assist the students in the task of documenting the board content by removing the objects in front of the board is highly desirable. In this paper, we have developed the method to remove occlusion present in front of board by video inpainting and further we used even odd interlacing and contour formation to improve the results.
