Abstract:
Edge-selective intra coding may include encoding a first input block, generating a first reconstructed block by decoding the first encoded block, determining a reconstruction error block based on a difference between the first input block and the first reconstructed block, identifying a second input block from the first input frame, and determining a plurality of refined context pixels. Determining a plurality of refined context pixels may include identifying a plurality of context pixels from the reconstruction error block, generating a plurality of encoded context pixels by encoding the plurality of context pixels, generating a plurality of reconstructed context pixels by decoding the plurality of encoded context pixels, and adding at least a portion of the reconstruction error block and the plurality of reconstructed context pixels. The method may include generating a second encoded block by encoding the second input block based on the plurality of refined context pixels.
