From 6fa47a5f16cb5631713ccc03d9b11f5345564abe Mon Sep 17 00:00:00 2001 From: Deb Mukherjee Date: Mon, 16 Jan 2012 11:21:12 -0800 Subject: Adds support for enhanced interpolation for subpel motion using an 8-tap filter. The results with 3 different 8-tap filters on the derf set are in: http://www.corp.google.com/~debargha/vp8_results/enhinterp.html The one that gives the most gain achieves an overall gain of about 0.6%. The results for a set of 12 hd (720p) videos are in: http://www.corp.google.com/~debargha/vp8_results/enhinterp_hd.html with max gain of 0.55% with the same filter. The best filter apparently achieves the best trade-off between pass band ripple and stop band attenuation.
