Lossy data compression with conditional reconstruction reinfinement |
摘要 |
<p>Methods of encoding and decoding media, for example video, using conditional reconstruction refinement are described. The encoding and decoding relies upon predictions that are based on previously encoded and decoded samples. Prediction information identifies the previously reconstructed samples upon which a prediction is to be based and is available to both the encoder and decoder. On the basis that a previously-reconstructed sample is going to be used as source data for a prediction, the encoder refines that reconstructed sample, uses the refined reconstructed sample for the prediction, and encodes refinement data to enable the decoder to also refine the previously-reconstructed sample during decoding. In some cases, a reconstructed sample may be refined more than once. Various flags or bits may be used to signal when refinement is enabled or disabled and may be signaled at various hierarchical points in the coding structure.</p> |
