In this paper, we present a spatially improved post-processing algorithm for compressed video. We note that blocking artifacts and ringing artifacts in compressed video is caused by 8?8 DCT and 16?16 macroblock based motion compensation. For overcoming them, we combine the projection method with the regularized filter. In Addition, an image resolution enhancement algorithm using spatially invariant PSF is represented. The simulation results show that the proposed algorithms better than the exist deblocking filter and bicubic interpolation approach.
