This paper presents a new video coding method which improves PSNR of decoded pictures by using additional information. Firstly, we show a pixel shift effect which brings PSNR improvement by composing multiple compressed images extracted from an original image and, as an application of the pixel shift effect, we then propose a video coding method which sends higher precision motion vectors to a decoder as additional information. We especially focus on how to select effective motion vectors at an encoder and how to decide mixture of decoded pictures for improving PSNR. Finally, we show experimental results that present improving R-D characteristics of H.263+. |
