| Popis: | We propose a novel video coding paradigm with wavelet image size reduction and wavelet super resolution (SR) reconstruction for the pre - and post-processing of a conventional MPEG-4 advanced video coding (AVC) | H.264 codec. The proposed method features the wavelet SR reconstruction in the post-processing can ensure stability and precision by using SR reconstruction parameters which are adaptively optimized with the original image on local SR reconstruction in the pre-processing. Experimental results showed that our proposed method has a higher objectively measured peak signal-to-noise ratio and outputs images with a better subjectively evaluated appearance than the MPEG-4 AVC | H.264 codec without this paradigm. |
