      Add function to compute skin map for a given block, as its
      used in several places (cyclic refresh, noise estimation, and denoising).

      vp9 denoiser: Re-evaluate ZEROMV after denoiser filtering. · 5b0ddb93
      Marco authored
      For denoising, and for noise level above threshold, re-evaluate
      ZEROMV for mode selection after denoising.
      Current change only does this check if selected best mode (before denoising)
      was intra.

      Fix to denoiser with dynamic resize. · 86ede509
      Marco authored
      Temporary fix to denoiser when dynamic resizing is on.
       -Reallocate denoiser buffers on resized frame.
       -Force golden update on resized frame.
       -Don't denoise resized frame, and copy source into denoised buffers.

      Code refactor on InterpKernel · 7186a2dd
      Zoe Liu authored
      It in essence refactors the code for both the interpolation
      filtering and the convolution. This change includes the moving
      of all the files as well as the changing of the code from vp9_
      prefix to vpx_ prefix accordingly, for underneath architectures:
      (1) x86;
      (2) arm/neon; and
      (3) mips/msa.
      The work on mips/drsp2 will be done in a separate change list.

      This is also an intermediate step towards adding back the

      Refactor mc reference block fetch in denoiser · a0be730e
      Jingning Han authored
      This commit refactors the motion compensated reference block fetch
      process in denoiser. It skips the stage that generates motion
      compensated reference block if denoiser decides to use copy block
      mode. For high motion clips, this could speed up the denoising
      process by about 10%.

      Add support for setting byte alignment on the Y, U, and V plane of the

      1024. A value of 0 sets legacy alignment.

      Add SSE2 code and unit test for VP9 denoiser. · 80465dae
      JackyChen authored
      This SSE2 is based on VP8 denoiser's SSE2 code. In VP8, there are
      only 16x16 blocks in denoiser, while in VP9, there are 13 different
      block sizes.
      By adding this SSE2 code, the improvement of encoder speed is around
      20%(using C code vs using SSE2 code), vary for different clips.
      The unit test for VP9 denoiser is to confirm that the SSE2 code is
      bit-exact with the C code. The unit test covers all block size.

      When calculating delta in VP8 denoiser, since the block size is fixed to 16x16,
      the divisor is 256, which is the number of the pixel.
      But in VP9, the block size varies, the divisor should correspond to the block
