      Rework base range entropy coding in level map system · 87b01b5a
      Jingning Han authored
      Replace the truncated geometric distribution model with the grouped
      leaves structure for more efficient probability modeling.
      Each group has its own Geometric distribution
      
      This give us 0.2% gain on lowres

      Rework txk_type indexing system for chroma component · 19b5c8fa
      Jingning Han authored
      Use the row and column indexes to fetch txk_type, which allows the
      chroma components to derive the tx type from the corresponding luma
      components. It improves the coding performance of txk-sel by 0.18%.

      cb4x4: Move sub-4X4 block sizes behind chroma flags. · 81ec2619
      Timothy B. Terriberry authored
      cb4x4 itself should not require these sizes.
      
      This simplifies compatibility with other experiments, since we can
      first make them work with cb4x4 (which is now on by default), and
      then worry about chroma_sub8x8 and chroma_2x2 (which is not) in
      separate steps.
      
      Encoder and decoder output should remain unchanged.

      Add gen_txb_cache() and it's related functions · 2affb3b0
      Angie Chiang authored
      This function pre-generate counts/magnitudes of each level map
      such that we don't have to re-calculate the counts/magnitudes
      while doing the optimization.

      Add txk_sel exp · cd9b03fb
      Angie Chiang authored
      This will separate the transform kernel selection from lv_map
      experiment such that we can evaluate each feature's performance
      separately
      
      Note that txk_sel is build on top of lv_map
