    Rework coeff probability model update for rtc coding · 8fe50191
    Jingning Han authored
    This commit reworks the ONE_LOOP_REDUCED coefficient probability
    model update process. It allows model update for every coefficient
    across the spectrum at a coarser resolution, instead of performing
    precise update only for certain subset of probability models.
    The overall runtime remains nearly same (<1% change) for speed -6.
    The compression performance is improved by 7.5% in PSNR for speed
    -5 and 4.57% for speed -6, respectively.
