      Change to limit the mv search range · c4048dbd
      Yaowu Xu authored
      As the pixel values beyond image border are duplicates of pixels
      on edge, the change limits the mv search range, any mv beyond
      the limits no longer produce new/different prediction values
      as entire block with pixels used for subpel interpolation are
      outside image border.

      Adding ss_size_lookup table. · 8db2675b
      Dmitry Kovalev authored
      Removing the old one bsize_from_dim_lookup. Now we have a way to determine
      block size for plane using its subsampling values (ss_size_lookup). And
      then we can find the number of pixels in the block (num_pels_log2_lookup).

      Some minor cleanups for efficiency · 94c481f9
      Deb Mukherjee authored
      Implements some of the helper functions more efficiently with
      lookups rathers than branches. Modeling function is consolidated
      to reduce some computations.
      
      Also merged the two enums BLOCK_SIZE_TYPES and BlockSize into
      one because there is no need to keep them separate (even though
      the semantics are a little different).
      
      No bitstream or output change.

      Enable recursive partition down to 4x4 · 1f26840f
      Jingning Han authored
      This commit allows the rate-distortion optimization recursion
      at encoder to go down to 4x4 block size. It deprecates the use
      of I4X4_PRED and SPLITMV syntax elements from bit-stream
      writing/reading. Will remove the unused probability models in
      the next patch.
      
      The partition type search and bit-stream are now capable of
      supporting the rectangular partition of 8x8 block, i.e., 8x4
      and 4x8. Need to revise the rate-distortion parts to get these
      two partition tested in the rd loop.

      Add joint motion search in comp_inter_inter mode(experiment) · 9f5811c2
      Yunqing Wang authored
      In current code, motion vectors got from single prediction mode are used
      in compound prediction mode directly. These motion vectors may not give
      accurate prediction since they are searched independently. In this patch,
      we took Pascal's suggestion, and did joint motion search in compound
      prediction mode to find better motion vectors in this situation.
      Test results:
      Overall PSNR: 0.570%(derf), 0.918%(stdhd);
      SSIM: 0.572%(derf), 1.009%(stdhd);
      
      The encoder is a little slower. This can be improved since some c
      code is used in motion search.

      Extend left/above partition context to per mi(8x8) · 4a88ad89
      Jingning Han authored
      Update and buffer left/above partition information context per 8x8
      block. This allows to further enable recursive partition down to
      4x4 block size, and hence deprecating I4X4_PRED and SPLITMV.
      
      This commit also fixes a context buffer swap/restore issue in 32x32
      partition type search. This gives 0.1% performance gain for derf/yt.
      Will refactor the superblock partition type search into recursion
      form.

      Contextual entropy coding of partition syntax · ff2b8aa2
      Jingning Han authored
      This commit enables selecting probability models for recursive block
      partition information syntax, depending on its above/left partition
      information, as well as the current block size. These conditional
      probability models are reasonably stationary and consistent across
      frames, hence the backward adaptive approach is used to maintain and
      update the contextual models.
      
      It achieves coding performance gains (on top of enabling rectangular
      block sizes):
      derf:   0.242%
      yt:     0.391%
      hd:     0.376%
      stdhd:  0.645%

      Recursive partition syntax coding · 90a91cc6
      Jingning Han authored
      Enable recursive partition information coding from SB64X64 down to
      MB16X16. The bit-stream syntax is now supporting rectangular block
      sizes. It starts from SB64X64 and recursively describes the partition
      type of the current block. If the partition type is PARTITION_NONE,
      the block is coded as a single unit; if it is PARTITION_HORZ or
      PARTITION_VERT, the block is segmented into two independently coded
      rectangular units, with no further partition needed; otherwise, the
      block is segmented into 4 square blocks. i.e., PARTITION_SPLIT case,
      each can be potentially further partitioned.
      
      Forward adaptive probability modeling is used for the partition
      information coding, conditioned on the current block size.

      Convert subpixel filters to use convolve framework · 7a07eea1
      John Koleszar authored
      Update the code to call the new convolution functions to do subpixel
      prediction rather than the existing functions. Remove the old C and
      assembly code, since it is unused. This causes a 50% performance
      reduction on the decoder, but that will be resolved when the asm for
      the new functions is available.
      
      There is no consensus for whether 6-tap or 2-tap predictors will be
      supported in the final codec, so these filters are implemented in
      terms of the 8-tap code, so that quality testing of these modes
      can continue. Implementing the lower complexity algorithms is a
      simple exercise, should it be necessary.
      
      This code produces slightly better results in the EIGHTTAP_SMOOTH
      case, since the filter is now applied in only one direction when
      the subpel motion is only in one direction. Like the previous code,
      the filtering is skipped entirely on full-pel MVs. This combination
      seems to give the best quality gains, but this may be indicative of a
      bug in the encoder's filter selection, since the encoder could
      achieve the result of skipping the filtering on full-pel by selecting
      one of the other filters. This should be revisited.
      
      Quality gains on derf positive on almost all clips. The only clip
      that seemed to be hurt at all datarates was football
      (-0.115% PSNR average, -0.587% min). Overall averages 0.375% PSNR,
      0.347% SSIM.
