## 抄録

Motion Estimation (ME) is a key performance bottleneck of H.265/HEVC encoding. In implementing ME, a fixed or bounded complexity is often desired for efficient pipelining and parallelism. We present a fixed-complexity mode filtering algorithm to reduce the complexity of fractional ME (FME). Firstly, a layer filtering is applied to select the mode candidates. Secondly, the ratio of integer-fractional ME costs (R_{f/i}) is defined and the confidence interval of R_{f/i} is utilized for further mode selection. Finally, an algorithm to fix the complexity is applied. Experimental results show that the FME encoding time is reduced by 83.3% with slightly BD-rate increase.
