      Refinements on modelcoef expt to reduce storage · 07443f15
      Deb Mukherjee authored
      Uses more aggrerssive interpolation to reduce storage for the
      model tables by almost more than half. Only 48 lists of probs are
      stored (as opposed to 128 before), corresponding to ONE_NODE
      probabilities of:
      1,
      3, 7, 11, ..., 115, 119,
      127, 135, ..., 247, 255.
      
      Besides, only 1 table is used as opposed to 2 before. So the overall
      memory needed for the tables is just 48 * 8 = 384 bytes.
      
      The table currently used is based on a new Pareto distribution with
      heavier tail than a generalized Gaussian - which improves results on
      derf by about 0.1% over a single table Generaized Gaussian.
      
      Results overall on derfraw300 is -0.14%.

      Enable bit-stream support to 8x4 and 4x8 partition · 810b612c
      Jingning Han authored
      The recursive partition type search is enabled down to 4x4, 4x8 and
      8x4, followed by the corresponding rate-distortion optimization for
      the per-partition encoding mode decisions.
      
      The bit-stream writing/reading synchronized in supporting the
      rectangular partition of 8x8 block.
      
      This provides above 1% coding performance gains on derf.
      
      To do next:
      1. re-design the rate-distortion loop for inter prediction below 8x8.
      2. re-design the rate-distortion loop for intra prediction below 4x4.
      3. make the loop-filter aware of rectangular partition of 8x8 block.
      4. clean the unused probability models.
      5. update default probability values.
