  • 摘要:Video restoration for blurred images is the significant challenge in Image processing. The video is restored using group based sparse representation. Video restoration is the operation of taking a corrupted/noisy video and estimating the clean original image. A Restoration method includes a motion-compensated de-noising. Digital compression artifacts and de-blocking are suppressed or masked. The group consists of non-local patches with similar structures and establishes a novel sparse representation modelling called Group Based Sparse Representation. Group Based Sparse Representation sparsely represents images in a unified framework. Thus this simultaneously enforces the local and non-local sparsity of self-similarity in images. For dictionary learning DCT technique is used for efficient restoration. Group Based Sparse Representation modelling performs peak signal-to-noise ratio. An experimental results show the performance of the proposed system. Thus this method is good in the video restoration concepts.
