Zusammenfassung

It has been proven that performance of video coding at low bit rates can be improved by down-sampling a video before compression and up-sampling it after decompression. The down-sampling based coding (DBC) provides more bit budget for DCT coefficients, which preserve more high order coefficients. In this paper we propose a new DBC which uses a modified example-based super-resolution (SR) algorithm to restore the original resolution of down-sampled video signals. Experiments have shown the proposed scheme achieve PSNR improvement and better visual quality at low bit rates as compared with the H.264/AVC video coding, as well as the DBC using a general locally linear embedding (LLE) method as in.
