2012-01-30RTCD: add variance functionsJohn Koleszar
This commit continues the process of converting to the new RTCD system. Change-Id: Ie5c1aa480637e98dc3918fb562ff45c37a66c538
2011-08-22Reclassify optimized ssim calculations as SSE2.Fritz Koenig
Calculations were incorrectly classified as either SSE3 or SSSE3. Only using SSE2 instructions. Cleanup function names and make non-RTCD code work as well. Change-Id: I48ad0218af0cc51c5078070a08511dee43ecfe09

2011-07-26cosmetics: consistently use [u]int64_tJames Zern
Removes mixed usage of (unsigned) long long and INT64. Fixes Issue #208. Change-Id: I220d3ed5ce4bb1280cd38bb3715f208ce23cf83a

2011-05-03change to use fast ssim code for internal ssim calculationsYaowu Xu
The commit also removed the slow ssim calculation that uses a 7x7 kernel, and revised the comments to better describe how sample ssim values are computed and averaged Change-Id: I1d874073cddca00f3c997f4b9a9a3db0aa212276
2011-04-07fixed an overflow in ssim calculationJim Bankoski
This commit fixed an overflow in ssim calculation, added register save and restore to make sure assembly code working for x64 platform. It also changed the sampling points to every 4x4 instead of 8x8 and adjusted the constants in SSIM calculation to match the scale of previous VPXSSIM.

2010-09-09Use WebM in copyright notice for consistencyJohn Koleszar
Changes 'The VP8 project' to 'The WebM project', for consistency with other webmproject.org repositories. Fixes issue #97. Change-Id: I37c13ed5fbdb9d334ceef71c6350e9febed9bbba
2010-06-18cosmetics: trim trailing whitespaceJohn Koleszar
When the license headers were updated, they accidentally contained trailing whitespace, so unfortunately we have to touch all the files again. Change-Id: I236c05fade06589e417179c0444cb39b09e4200d
