Add a speed feature to give the tighter partition search range. Before partition search, calculate the histogram of the partition sizes of the left, above and previous co-located blocks of the current block. If the variance of observed partition sizes is small enough, adjust the search range around the mean partition size, which will be tigher. The feature is currently turned on at speed 2. Experiments on sample youtube clips show on average the runtime is reduced by 3-7%. For hard stdhd clips: park_joy_1080p @ 15000kbps: 509251 ms -> 491953 ms (3.3%) pedestrian_area_1080p @ 2000kbps: 223941 ms -> 214226 ms (4.3%) The PSNR performance is changed: derf: -0.112% yt: -0.099% hd: -0.090% stdhd:-0.102% Change-Id: Ie205ec5325bf92ec5676c243e30ba9d0adca10f2 |
