In this study, an online active learning system based on digital video watermarking techniques has been developed. In the developed system, teachers can grasp how much the students' self studies progress by utilizing the markers embedded into the video learning materials. When a student logs in the web-based system and watches the video materials, the embedded markers can be extracted automatically and sent to the servers on the teachers's side. It is quite difficult to recognize the embedded markers on the stego video materials. The markers can be extracted quite faster than the previously proposed watermarking schemes since image feature quantities such as AKAZE are employed to embed the watermarks. In addition, the embedded watermarks can be extracted successfully by utilizing these image feature quantities.
