Outline of Final Research Achievements

Reducing the size of the video by encoding is a technique necessary for efficient transmission. However, if the compression ratio increases, the visibility will be deteriorated. The aim of this research is to develop a technique that can transmit visually natural videos even at the high compression rate. We studied encoding with polynomial representation, encoding by image generation, encoding by object extraction, and have developed a method that can produce visually natural videos compared with the conventional methods.
