Video scal- ing is used in a wide range of applications from broadcast, medical imaging and high-resolution video effects to video surveillance, and video conferencing. Many algorithms have been proposed for these applications, such as piecewise polynomial kernels and windowed sinc kernels. The sum of three shifted versions of a B-spline function, whose weights can be adjusted for different applications, is adopted as the main filter. The proposed algorithm is confirmed to be effective on image scaling ap- plications and also verified by many widely acknowledged image quality measures. The reconfigu- rable hardware architecture constitutes an arbitrary scaler with low resource consumption and high performance targeted for field programmable gate array （FPGA） devices. The scaling factor can be changed on-the-fly, and the filter can also be changed during runtime within a unifying framework.展开更多

The overall architecture and the design of the major functional units, such as the motion vector decoder, the predictor, and the mixer, were discussed. Based on the exploitation of the special characteristics inherent in the motion compensation algorithm, the motion compensation module and its functional units adopt various novel architectures in order to allow the module to meet real-time constraints. This solution resolves the problem of high hardware costs, low bus efficiency and complex control schemes in conventional designs.展开更多
