In this paper, we consider high-resolution multi-sprite generation and its application to background sprite coding. Firstly, we propose an approach to partitioning a video sequence into multiple background sprites and selecting an optimal reference frame for each sprite range. This approach groups images that cover a similar scene into the same sprite range. We then propose an iterative regularized technique for constructing a high-resolution sprite in each sprite range. This technique determines the regularization parameter automatically and produces sprite images with high visual quality. Due to the advantages of high-resolution multi-sprites, a high-resolution sprite coding method is also presented and it achieves high coding efficiency.
