| Abstract: |
In this paper, we proposed a new scheme of forming quarter-pixel reference of LL band for in-band video coding with spatial scalability. The recently proposed leaky motion compensation and mode-based temporal filtering methods [5] have reduced the drifting error dramatically. However there still remains drifting error because of the use of high quality reference and the difference between high quality and low quality references [5]. In our method, a new reference is formed which gives PSNR higher than the low quality reference. The new reference is used instead of low quality reference in leaky and mode-based methods and experimental results show that improvement can be achieved in PSNR comparison with the existed ones. |
