Abstract:

With enough input of low resolution video sequences, the algorithm of spacetime superresolution reconstruction proposed by Shechtman E et al. can achieve satisfactory result. Because it’s hard to obtain enough low resolution video sequences of the same dynamic scene in practice, the application of this algorithm is limited. A new algorithm of spacetime superresolution reconstruction is proposed, in which, a high temporal resolution video sequence is reconstructed by utilizing the algorithm proposed by Shechtman E et al, and the spatial resolution of the high temporal resolution video sequence is improved by utilizing the improved iterative back projection algorithm. Experiments show that the proposed algorithm can effectively reconstruct a high spacetime resolution video sequence with limited low resolution video sequences.
