| Abstract: |
In this paper, a new approach for an improved video coding scheme is presented, which combines hybrid video coding and texture synthesis based on motion distribution statis- tics. Considering that the utilized texture synthesis approach provides high-quality visual results, while it is developed only for synthesizing the identified DTs within a certain area, a new framework is presented, which allows to identify of areas for synthesis and combine conventional coding with synthesis. Also, a new representation and compression of synthesis parameters is presented, which is required due to the updated coding structure. When combining the proposed approach with conventional en- coder (HEVC reference software, HM 16.6), significantly reduced bit rates of the compressed video sequences with the texture replaced can be obtained. Moreover, because the synthesized textures have similar perceptual characteristics to those of the original textures, the video sequences with the texture replaced are also visually similar to the original sequences. Video results are provided online to allow assessing the visual quality of the tested content. |
