Abstrakt:With raising amount of e-learning materials such as lecture videos or on-line video courses, we decided to develop an application, which can help students or content creators in their effort to prepare study materials. Main goal of our application is to create slides from given video, depicting a black or white board without any occluding objects such as lecturer standing in front of this board. Slides will contain valid information from key frames of the given lecture video. Based on the assumption, that the board is static in the video, this is done by extracting the board from video frames, which is then segmented into equally sized rectangular cells. These cells are stored and the change of information inside them is tracked. Afterwards, the final image is created from saved cells when all cells are sufficiently stable.
