ABSTRACT:
A novel method and structure for the implementation of Half Pixel Filtering and Block Averaging that are efficient for implementation on a general purpose CPU. The number of required operations are reduced by operating on multiple pixels simultaneously using sliced arithmetic, while maintaining full accuracy. In certain embodiments, the number of operations are further reduced by compromising full accuracy. This approximation is applicable to decoding of bi-directional frames.
