Image Registration in E-Learning Applications

Real-time video transmission is considered as an important way for information broadcasting. One noticeable example in this area is E-leaning applications, which is based on real-time video processing and transmission. On the other hand, the process of registration is a fundamental component in automatic image and video processing. In our previous work, we implemented a new method for cut detection technique based on dominant lines and angles. This paper introduces a new video registration technique that uses dominant angles extracted from edge information of the video frames in one shot. To the best of our knowledge, it is the first works done for registration in E-learning applications. This method is compatible with our application’s requirements and has a low complexity and high speed. We compare our method against three established techniques and present our results using different video sequences
