Method and system for sampling video data |
摘要 |
A method and system for sampling video data uses re-sampling filters having lengths optimized relative to a quantization parameter of video processing. The method uses modeling of an optimal length of the re-sampling filter as a function of the quantization parameter to derive empirical formulas and a look up table for optimal lengths of re-sampling filters. The resulting re-sampling filters are selectively adapted for sampling video data having different bit rates.
