From: Yunqing Wang Date: Tue, 16 Feb 2016 22:33:18 +0000 (-0800) Subject: Do sub-pixel motion search in up-sampled reference frames X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=342a368fd489d4bb2fd2ef9189a933ff7b643d64;p=libvpx Do sub-pixel motion search in up-sampled reference frames Up-sampled the reference frames to 8 times in each dimension using the 8-tap interpolation filter. In sub-pixel motion search, use the up-sampled reference frames to find the best matching blocks. This largely improved the motion search precision, and thus, improved the compression quality. There was no change in decoder side. Borg test and speed test results: 1. On derflr set, Overall PSNR gain: 1.306%, and SSIM gain: 1.512%. Average speed loss on derf set was 6.0%. 2. On stdhd set, Overall PSNR gain: 0.754%, and SSIM gain: 0.814%. On hevchd set, Overall PSNR gain: 0.465%, and SSIM gain: 0.527%. Speed loss on HD clips was 3.5%.
