For all video applications, large amounts of data are processed within a bounded time. These data are usually stored in a low-cost slow external DRAM which results in high memory bandwidth requirement. The memory bandwidth will dominate the system performance, especially for applications running on embedded systems. In this paper, we propose an effective dictionary-based compression and de-compression...
This paper presents a scheme which combines the cubic spline interpolation (CSI) with standard H.264 codec in order to further improve the compression ratio at the same video quality. The CSI function is first applied to down-sample video frames to one quarter of the original video frames. The standard H.264 is then applied on those down-sampled frames to complete the encoding process. One can reconstruct...
