Cloud-Based Video Course Recording Model for WE-TUTOR

摘要

A cloud-based video course recording model is proposed in this paper to record and deal with classroom information in the learning management system (LMS). In the developed model, a new foundations key frame description technology (FKD) has been developed. A cloud-based key frame description library (CKDL) has been improved to raise the speed of retrieval. At the same time, a novel approach has been developed to store the foundations key frame of video course and a related extracting technique has been built to show the transferred video on the client. The results and experiments has demonstrated that the proposed model is effective in frame based video retrieval in the system of WE-TUTOR.
