Recent developments on sparse representation based approaches have demonstrated promising results for VS. However, these existing approaches treat each frame indepen- dently, so the performance can be greatly influenced by each individual frame. In this paper, we formulate the VS problem with a collaborative representation model to take the visual similarity of adjacent frames into consideration. To be specific, during the procedure of reconstruction, both each individual frame and their adjacent frames are reconstructed col- laboratively, so the impact of an individual frame can be weakened. In addition, a greedy iterative algorithm is designed for model optimization, where the sparsity and the aver- age percentage of reconstruction (APOR) are adopted to control the iteration.
