A novel method for semi transparency effect in academic videos

Abstract

In academic videos the written content is often hidden by instructor hand itself. The problem of content obscuring can be commonly seen in tutorial videos. This problem is addressed by making transparent background surface using interactive pen or pen digitizers. No work has been done so far to achieve transparency effects in paper and whiteboard based tutorial videos without any additional hardware. Hence, this paper introduces a semi transparency effect in a paper and whiteboard based tutorials. This work is well suited for large amount of already recorded paper and whiteboard based tutorial videos available on the internet. The proposed method uses combined averaging methods with background modeling techniques and does not rely on interactive pen displays or any other costly hardware setup. The experimental results show the proposed method is well suited for the tutorial videos.
