Multiple-thread long-term memory scheme for efficient video coding

It has been shown that a background memory can be used to improve the coding efficiency of a video codec. However, this solution is restricted to sequences with a stationary background. Such a restriction seriously limits the application of the background memory scheme. The authors combine the long-term memory scheme with a multiple-thread memory mechanism to boost the coding efficiency for a much wider application range. The experimental results confirm the effectiveness of the proposed method
