Statistical performance comparisons of computers Performance comparison has been continuously hampered by the variability of computer performance. It is important to know the confidence of a comparison result. We proposed a statistically rigorous framework (as well as a referece software) to correctly provide confidence for performance comparison.
Video encoder without integer-pel search The integer-pel search of motion estimation, which searches a suitable integer-pel reference position, was considered to be crucial for video encoding. It even occupies over 50% of the overall encoding time when adopting the full search scheme. We observe an interesting phenomenon that video sequences of high resolution can be encoded effectively and efficiently even without integer-pel search.
