2018-12-06Improve rd_variance_adjustment() for low variance blocks.Paul Wilkins
Change the cross over point for switching between per pixel and per block variance numbers when comparing reconstruction and source complexity. This improves the accuracy of the comparison for low variance regions, For example, recon and source may both have an integer per pixel variance of 1, but one of these may actually be be 1.01 and the other 1.99. The reason for using per pixel at all was because this number is already available for the source block so does not need to be recomputed here. Changing the threshold from >0 to >100 for using per pixel values will thus cause a little extra work for some blocks. With my default runs on derf and nf sets their is a net gain as follows: (-ve = better, Overal PSNR, SSIm, PSNR-HVS) derf low res -0.106, -0.107, -0.093 midres -0.000, -0.021, 0.001 hd res -0.198, -0.190, -0.282 nf2k -0.090, -0.088, -0.077 Change-Id: I53ef514fe1c35ee3f08c64e9b22fc05fc7fe5887

2018-11-29Consider mv inconsistency in single_motion_searchAngie Chiang
This is still a work-in-process. nb_full_mvs and lambda are set to zero for now, which means mv inconsistency penalty is zero while doing the mv search. Change-Id: I18680413d748fbdb9a33621f92f83e021036a3ab
