Fixes some scaling issues. Adds an option to only compute the dct on the low-low subband for 32x32 and 64x64 blocks using only a single 16x16 dct after 1 and 2 wavelet decomposition levels respectively. Also adds an option to use a 8x8 dct as building block. Currenlty with the 2/6 filter and with a single 16x16 dct on the low low band, the reuslts compared to full 32x32 dct is as follows: derf: -0.15% yt: -0.29% std-hd: -0.18% hd: -0.6% These are my current recommended settings, since the 2/6 filter is very simple. Results with 8x8 dct are about 0.3% worse. Change-Id: I00100cdc96e32deced591985785ef0d06f325e44 |
